Sewall Wright’s population structure statistic, FST, measured among samples of world populations is often 15% or less. This would indicate that 85% of genetic variation occurs within groups while only 15% can be attributed to allele frequency differences among groups. In this paper, we show that this low value reflects strong biases that result from violating hidden assumptions that define FST. These limitations on FST are demonstrated algebraically and in the context of analyzing dinucleotide repeat allele frequencies for a set of eight loci genotyped in eight human groups and in chimpanzees. In our analyses, estimates of FST fail to identify important variation. For example, when the analysis includes only humans, FST = 0.119, but adding the chimpanzees increases it only a little, FST = 0.183. By relaxing the underlying statistical assumptions, the results for chimpanzees become consistent with common knowledge, and we see a richer pattern of human genetic diversity. Some human groups are far more diverged than would be implied by standard computations of FST, while other groups are much less diverged. We discuss the relevance of these findings to the application of biological race concepts to humans. Four different race concepts are considered: typological, population, taxonomic, and lineage. Surprisingly, a great deal of genetic variation within groups is consistent with each of these concepts. However, none of the race concepts is compatible with the patterns of variation revealed by our analyses.

This article examines a controversial report that focused negatively on mixed heritage children born and raised in the city of Liverpool. The official title was: Report on an Investigation into the Colour Problem in Liverpool and Other Ports. The social researcher was Muriel E. Fletcher, who had been trained in the Liverpool School of Social Science at The University of Liverpool in the early 1920s.  The report was published in 1930 amid controversy for its openly stigmatizing content of children and mixed heritage families of African and European origin.  It could be deemed the official outset in defining Liverpool’s ‘half castes’ as a problem and blight to the “British way of life” in the city.

…Numerous ‘intellectual’ views held by white commentators, either consciously or unconsciously, or even a mixture of the two if we take the example of Ralph Williams, related to racialised discourse and they appear to have had a strong bearing on the complex nature of the anti-Black riots in 1919 Liverpool.  An outcome of this was to further stigmatise Black-white sexual relations in which the offspring of those liaisons were effectively branded as less-than human, degenerate, only to be despised and scorned by mainstream society.  Again, imbued in the rhetoric, was the notion of hybridity between Black-white unions being anomalous, which echoed the philosophy of the Eugenics Movement in Britain (Park 1930; Searle 1976: 43)….

…The aftermath of the anti-black riots in 1919 saw the problem of ‘half-caste’ children in Liverpool take on greater significance and the issue developed into a much discussed and analysed topic (King and King 1938; Rich 1984, 1986; Wilson 1992).  The debates engendered ‘intellectual’ legitimisation of racialised ideology that effectively produced a climate of opinion that sought to reduce the sexual interaction between Black and white people.  The corollary of this was to further stigmatise the mixed heritage population as a social problem that society had to be rid.  Some of the key racialised stereotypes associated with the term ‘half-caste’ will be made clearer through an examination of key Liverpool-based philanthropic organizations, which were set up to deal specifically with the ‘social problem’ caused by the progeny of Black and white relationships…

…Arguably, in relation to the Liverpool Black experience, the pivotal stigmatising report to be published in the history of poor ‘race relations’ in Liverpool was in regard to mixed heritage children and their family structure. Muriel E. Fletcher (1930), who had the full backing of Ms. Rachel Fleming, a prominent eugenicist (Jones 1982), and other contemporary pseudo-scientific intellectuals, conducted the research on behalf of the Liverpool Association for the Welfare of Half-Caste Children and published in 1930 a document entitled a Report on an Investigation into the Colour Problem in Liverpool and other Ports. It is a sociological report produced in the late 1920s and can be regarded as a nadir in the Liverpool mixed heritage population’s struggle to secure a positive social identity.  This ubiquitous racialised stigma was grounded in the eugenicist tradition of Sir Francis Galton (1822–1911) and the Eugenics Society. The society viewed humans in terms of being ‘inferior’ and ‘superior’ in stock (Jones 1982), and it is an overt philosophy throughout the report. Using eugenicist techniques, it is apparent that Fletcher attempted to study the physical and mental quality of ‘half-caste’ children.  Implicit in the research is the idea that the African and white British/European offspring were an anomaly in terms of human breeding. Eugenicists believed selective breeding could improve the physical and mental quality of humans by, e.g., ‘controlling’ the spread of inherited genetic abnormalities (which led in this era, 1920–1930s, to eugenics being abused by the Nazi Party in Germany to justify the extermination of thousands of ‘undesirable’ or mentally and physically ‘unfit’ humans)…

…Fletcher argued that ‘half-caste’ women were particularly vulnerable in Liverpool as they naturally consort with ‘coloured men’.  She maintains that ‘half-caste’ women were regarded as virtual social outcasts whose only escape from a life of perpetual misery was to marry a ‘coloured man’. As the opportunity in marrying a white man was, for a ‘half-caste’ woman, a near impossibility.  Again Fletcher points out:

Only two cases have been found in Liverpool of half-caste girls who have married white men, and in one of these cases the girl’s family forced the marriage on the man (1930a: 21).

It should be pointed out that this negative reflection of ‘half-caste’ girls in Liverpool is a major theme throughout the Fletcher Report.  Certainly the experience of mixed heritage women would require and deserves a study in itself, if only due to the significance and importance of highlighting the perspective of mixed heritage women in the history of Liverpool.  However, what is important here and central to this historical social research is to provide an insight into the racialised stigma that has impacted all individuals of mixed heritage in the Liverpool Black experience in terms of their collective social identity in the context of the city…

British Eugenics and ‘Race Crossing’: a Study of an Interwar Investigation

British Eugenics and ‘Race Crossing’: a Study of an Interwar Investigation

New Formations

pages 66-78

Lucy Bland, Professor of Social and Cultural History

In 1937 a polemic entitled Half-Caste was published, heralding ‘the richness of hybrid potentiality’. Written by a self-defined Eurasian called Cedric Dover its opening pages indicated the extent of prejudice facing those of mixed race:

The ‘half-caste’ appears in a prodigal literature. It presents him … mostly as an undersized, scheming and entirely degenerate bastard. His father is a blackguard, his mother a whore … But more than all this, he is a potential menace to Western Civilisation, to everything that is White and Sacred…

This ‘prodigal literature’ included novels and ‘a vast mass of pseudo-science’ developed by ‘eugenists, anthropologists, sociologists and politicians’.  In the book’s Preface, written by British scientist Lancelot Hogben, it was eugenics that was singled out for condemnation: ‘An influential current of superstition (called National Socialism in Hitler’s Germany and Eugenics in England) claims the authority of science for sentiments which are the negation of civilised society’. Yet despite the negative tone of the Preface, and the reference to ‘pseudo-science’, Dover was clearly not uninfluenced by eugenics.  He cited a number of British eugenists in his ‘Acknowledgements’, and he dedicated his book to Ursula Lubbock (Mrs Grant Duff) an active member of Britain’s Eugenics Society. He also admitted: ‘I subscribe without qualification to the prevention of undeniably dysgenic matings … but not to the conceit that colour and economic success are indices of desirability’. His invocation of a different index of ‘desirability’ other than economic success was reminiscent of other socialists who espoused eugenics on their own terms.  Eugenics was sufficiently protean to be harnessed to different ideological beliefs, ranging from the ultra conservative to the social-reformist and socialist. What was new and unique about Dover’s particular take on eugenics was the centrality of the ‘half-caste’, who ‘must be regarded … as a portent of a new humanity—a portent to be encouraged by the stimulation of eugenical mixture …’

In contrast to his own positive eugenical reading, Dover recognised that most other exponents of eugenics in interwar Britain took a very different view of the ‘half-caste’, namely, as ‘potential menace to Western Civilisation’. Why did these eugenists (and indeed many of the British establishment) hold such a view? What did they think were the implications of the presence of the ‘half-caste’? What or who was unsettled by the presence of mixed race people? One way of exploring these concerns is through an analysis of a project set up by the British Eugenics Society to investigate what they called ‘race crossing’. An examination of this project not only throws light on the prevailing discourses on race differences and their measurement, whiteness, and Englishness, but it also enables us to test historian Barbara Bush’s claim that eugenics was ‘a strong element of inter-war racism’, and to get a clearer sense of the role played by British eugenics in the discussion and regulation of race…

‘The White Wife Problem’: Sex, Race and the Contested Politics of Repatriation to Interwar British West Africa

‘The White Wife Problem’: Sex, Race and the Contested Politics of Repatriation to Interwar British West Africa

Based on archival research in Ghana and Britain, this article documents the sustained but failed attempts of working-class West African seamen to repatriate to the colonies with their European wives during the interwar years. Colonial authorities crafted policies to prevent these couples from making British West Africa home because they feared that the presence of European women living ‘in native fashion’ with their African husbands would destabilise colonial race relations. After discussing the origins of this policy in the context of the 1919 race riots that swept Britain’s port cities, the article draws on the case of a West African man married to a German woman to illuminate how concerns about race, sex, gender, nationality and class informed the politics of repatriation to British West Africa during the interwar years.

[Excerpted from the chapter of the same name in the anthology, Homes and Homecomings: Gendered Histories of Domesticity and Return]

As the First World War came to a close, ‘black’ men from Britain’s overseas colonies and their white wives and lovers came to embody the fears and anxieties that gripped Britain’s economically depressed port cities. Black men were accused of taking jobs from white British men and stealing ‘their’ women. White women who partnered with black men were cast as depraved and immoral traitors, who selfishly prioritised their own sexual and material desires above the good of the nation. Working-class inter-racial couples became targets of abuse on the increasingly tense streets of Britain’s port cities and, when a series of violent race riots swept through the ports in the summer of 1919. they were largely blamed for their outbreak.  White mobs, ranging in size from a few hundred to several thousand, indiscriminately attacked black men, harassed and assaulted their white partners, and destroyed the multiracial settlements they called home. In the wake of the riots, some of these couples attempted to leave their hostile environs for the British colonies, especially in West Africa and the West Indies, where many of the men in question came from. Their desire to take up residency overseas, however, led lo the immediate implementation of a policy which I call the ‘policy of prevention’, designed to keep European women married to working-class black men out of the colonies. This was especially the case for British West Africa and marked an important shift from the prewar period, when colonial social conventions and their attendant racial taboos were the primary mechanisms that, at the very least, kept European women and black men from openly liaising with one another. During the interwar period, state power was also used to ensure that the West African colonies were kept free of such couples.

While the origins of the policy of prevention are to be found in the immediate aftermath of the 1919 race riots, it continued to guide colonial authorities’ decision-making processes throughout the interwar years. By and large, it was West African men who were domiciled in Britain and married to white British women that sought in the decision-making processes of colonial authorities. It also demonstrates that in contrast to settler colonial regimes, in places like Southern Rhodesia and South Africa, the administered colonies of British West Africa stopped short of implementing the most draconian forms of sexual segregation through the use of anti-miscegenation laws and barbaric extralegal measures such as lynching. Rather, to keep the colonies free of all but a handful of wealthy inter-racial couples, colonial authorities used a combination of strategies, including denying passports to the white wives of working-class African men, refusing to pay the cost of their passage to West Africa, and classifying them as ‘undesirable immigrants’ under the provisions of the colonies’ Immigration Restriction Ordinance. While not the focus of this chapter, these strategics were complemented by earlier but comparatively less vigilant efforts on the part of colonial administrators to bring an end to the far more frequent occurrence of sexual relationships between European colonial officers and African women through the use of official anti-concubinage circulars during the early twentieth century.’ This in turn helps to underscore the importance of paying attention to the spectrum of colonial anxieties that accompanied the gendered, racial and spatial configurations of mixed race couples, as well as the forms (illicit, casual, marital) their relationships took. Indeed, if we are to use panic and bureaucratic strong-arming as yardsticks, preventing European officers from cohabiting with African women was a far less pressing issue than keeping lawfully married working-class black men and white women out of the colonies.

Reflecting on the deep-seated anxieties surrounding the existence of inter-racial unions between black men and white women during the interwar years in Britain, Lucy Bland usefully suggests that, if we are to fully understand the complexity of inter-racial relationships during this period, we must undertake the difficult work of documenting the voices of the ‘women and men who negotiated their personal and sexual relationships in the face of a barrage of both official and cultural hostility’, while paying particularly close attention to ‘their experiences, the impact of prejudice upon them, and their strategies of survival and support’. Foregrounding their experiences in our analysis of the colonial archive provides a more complete view of the various worlds these couples were attempting to negotiate. Laura Tabili has done just this by charting the thwarted struggles of a handful of British and mixed-race British-Somali women to make the British Protectorate of Somaliland their home in the face of the exclusionary practices of colonial authorities who believed that the presence of these women living intimately among ‘native’ populations posed a ‘threat to colonial, racial and gendered hierarchies, and British credibility’. In what follows, I also take up Bland’s mandate and in so doing provide a broader historical context, indeed the precedent for understanding Tabili’s work on British Somaliland, by looking at the history of mixed-race couples who sought to make home in British West Africa during the interwar years.

Riots, repatriation and the policy of prevention

Although black communities and mixed marriages in Britain long predate the First World War. during the war itself increasing numbers of black seamen came to its ports from different parts of the world to fill the labour vacuum in the shipping industry that resulted from the drafting of white British men into the military. The majority of these seamen originated from Britain’s colonies in the West Indies and West Africa, as well as from India, the British Somaliland Protectorate and Aden. While seamen from India, known as tascars, had always made up a significant number of the colonised labour hired on British vessels, the contracts they were hired under greatly restricted their ability to reside in Britain; as a result, settlement rates were highest among seamen from the West Indies. West Africa, Somaliland and Aden. Ethnic settlement patterns differed from port to port; for instance, Liverpool was inhabited’ mostly by West Indians and West Africans, while Cardiff had a higher percentage of men from Aden and Somaliland. At the close of the war, most of these men, along with considerable numbers of demobilised soldiers from Ihe colonies, remained in the country’s seafaring districts. Together, they competed with white British men for an increasingly limited number of maritime jobs.

Economic hardship in the ports, created by the post-war depression and racialiscd job competition within the shipping industry, offers a compelling explanation of the underlying cause of the riots. In Jacqueline Jenkinson’s study of the 1919 riots, she examines a series of smaller riots between January 1919 and the outbreak of major rioting in June and finds that in each of the cases racial violence was a direct result of competition over jobs. Moreover, the initial incidence of racial violence that led to the outbreak of rioting in Liverpool in June was attribuied to tensions between black seamen and white foreign labour, in this case Scandinavians, who were in direct competition with each other for jobs not already taken by white British seamen. Yet it was the notion that black men were consorting with white women that garnered the most attention from the press, local and national authorities, as well as everyday observers. The ‘sex problem’, as one newspaper dubbed it. became a primary explanatory framework for understanding, and in many cases rationalising, the impetus behind the riots. The attention given to the ‘sex problem’ by contemporary observers, including policy makers, suggests that, in addition to job competition, anxieties over race and sex played an important role in the move towards proposing repatriation as an appropriate solution to the social and economic problems deemed responsible for the riots. Indeed, within days of the major outbreak of violence in June, local and national authorities began drawing up plans to repatriate black men to the colonics in an attempt to restore calm and order (and more specifically, racial order) to the port cities. The Colonial Office, however, feared that if the repatriations were handled inappropriately, they would cause instability by returning disgruntled men to the colonies. Disturbances had already broken out in Sierra Leone as early as July 1919 over the ill-treatment of black men in the British ports.” How much more unrest could be expected if the victims of the riots, many of whom had participated in the war effort, were forcibly returned to the colonies?

Anxious about the stability of the West African colonies, the Colonial Office not only insisted that the repatriation scheme be voluntary, it was also equally adamant that the white wives of ‘natives’ should be prevented at all costs from going to West Africa with their husbands. In fact, rioting had barely come lo a stop in June 1919, and the Colonial Office had already decided to refuse repatriation facilities to black men who insisted on returning with their white wives. Given that the men in question had no funds to repatriate themselves, let alone their wives, by refusing to pay passage fees, British authorities effectively made it impossible for black men who desired joint repatriation to return lo the colonies with their white wives. On 30 July 1919, this policy was solidified during a meeting at the Ministry of Labour, which had assumed responsibility for Ihe repatriation scheme. At the special insistence of the Colonial Office, the Ministry of Labour instructed the local committees responsible for facilitating the scheme in the seven main ports (Salford, Liverpool, Cardiff, Glasgow, Hull, South Shields and London), not to repatriate black men with their white wives. As one Colonial Office adviser later put it, the ‘white wife problem’ was, as the phrase suggests, particular to white women. This is underscored by the fact that the government agreed to pay the cost of repatriating the few black men, like Joseph Queashie from the Gold Coast, who were married lo black women. It is difficult to ascertain the exact number of West Africans and their white wives who were adversely affected by this policy, but the statistical information available suggests that their numbers were by no means negligible. In a survey conducted by the Liverpool Police shortly after the riots, a total of 188 men from British West Africa were identified as residing in Liverpool. The police, however, suspected that the actual number was much higher and suggested that the lower number reported was the result of ‘an exodus of negroes from the city to inland towns since the question of repatriation arose’ and added that ‘those who have not left are probably in hiding’. As Table 1 indicates, of the 188 West African men identified, twenty-one were married, eighteen of these to white women resident in Liverpool and three to African women who resided in West Africa. Of the eighteen men married lo white women, eleven were willing t0 be repatriated back to West Africa with their white wives.

The willingness of 50 per cent of married West Africans to accept repatriation compared to 47 per cent of single West Africans indicates that the authorities were wrong in believing that marriage to white women created ties to the metropole that could not be broken as easily as those of single men. Rather, it was the authorities” policy of prevention that kept these men in Britain because it barred them from returning to the colonies with their wives. Thus, if we are to understand fully the range of different imperatives that shaped the unwillingness of West Africans to be repatriated and ultimately led to the schemes’ widely recognised failure, we must acknowledge that, in addition to unsatisfactory remuneration packages and Ihe desire, indeed the right to remain in Britain, for some West Africans the policy of prevention was also a major factor. A representative from the Local Government Board said as much when he expressed his belief that “the white wife constituted a big difficulty.” The Colonial Office’s refusal to repatriate West Africans with their white wives contrasts sharply with its concession to allow black men from other parts of the British Empire, namely West Indians, to return home with their white wives at the…

White Women and Men of Colour: Miscegenation Fears in Britain after the Great War

White Women and Men of Colour: Miscegenation Fears in Britain after the Great War

This article examines miscegenation fears in Britain in the period after World War I, noting three dominant discourses: that miscegenation leads inevitably to violence between white and black men (focusing on the 1919 race riots), that these relationships involve sexual immorality (analysing the 1920 ‘Black Horror on the Rhine’, a case involving a white woman, a Chinese man and drugs and a trial of a white woman for killing her Egyptian husband) and that miscegenation has ‘disastrous’ procreative consequences. It is suggested that miscegenation stood as one British boundary marker, separating the nationally acceptable and the nationally threatening. The parties concerned–the ‘primitive’ man of colour, the white woman of a ‘low type’ and the ‘misfit’ offspring–were each pathologised in terms of their deviant sexuality. Yet interracial relationships did not decrease, quite the contrary. The move in Britain towards a more racially mixed community began in the years after the Great War, when certain white women made choices against the norms of respectable femininity.

The Genetic Structure of Admixed Populations

The Genetic Structure of Admixed Populations

Genetics
February 1, 1991
Volume 127, Number 2
pages 417–428

Jeffrey C. Long, Professor of Anthropology
University of New Mexico, Albuquerque

A method for simultaneously estimating the admixture proportions of a hybrid population and Wright’s fixation index, FST, for that hybrid is presented. It is shown that the variance of admixture estimates can be partitioned into two components: (1) due to sample size, and (2) due to evolutionary variance (i.e., genetic drift). A chi-square test used to detect heterogeneity of admixture estimates from different alleles, or loci, can now be corrected for both sources of random errors. Hence, its value for the detection of natural selection from heterogeneous admixture estimates is improved. The estimation and testing procedures described above are independent of the dynamics of the admixture process. However, when the admixture dynamics can be specified, FST can be predicted from genetic principles. Two admixture models are considered here, gene flow and intermixture. These models are of value because they lead to very different predictions regarding the accumulation of genes from the parental populations and the accumulation of variance due to genetic drift. When there is not evidence for natural selection, and it is appropriate to apply these models to data, the variance effective size (Ne) of the hybrid population can be estimated. Applications are made to three human populations: two of these are Afro-American populations and one is a Yanomamö Indian village. Natural selection could not be detected using the chi-square test in any of these populations. However, estimates of effective population sizes do lead to a richer description of the genetic structure of these populations.
