Sex-biased admixture in US genetic ancestry groups

We compared the patterns and extent of sex-biased admixture among the three US genetic ancestry groups by comparing the continental ancestry fractions – African, European, and Native American – seen for the X chromosomes versus the autosomes. For any given ancestry component, a relative excess of X chromosome ancestry is indicative of female-biased admixture, whereas an excess of autosomal ancestry reflects male-biased admixture26. This was only done for admixed individuals that had two or more continental ancestry fractions at >1.5% of the overall ancestry. Almost all individuals from the African American and Hispanic/Latino groups met this criterion, but only a small minority of European American individuals with Native American admixture did. African American and Hispanic/Latino ancestry groups showed marked patterns of sex-biased admixture, whereas the European Americans did not show any appreciable evidence of sex-biased admixture (Figure 2). The strongest pattern of sex-biased admixture was seen for Hispanic/Latino individuals, with female-biased Native American admixture and male-biased European admixture. African Americans show female-biased African ancestry and male-biased European ancestry.

Obviously this isn't news to anyone but its still interesting

most latam countries have euro ydna and amerindian mtdna

Do african americans usually claim Native ancestry? They have a little more than whites

Not often.

REgarding white americans i thought amerindian was higher in Southeast but it seems its higher in Pacific and MNT region.

Are we supposed to know what this means

The admixture of amerindian in whites?

[JMack]

European Americans are nearly full European on average, no comparison with European-Latin Americans. Apart from isolated countryside pockets in Brazil and Argentina (which I guess haven't been tested yet, at least in Brazil), very few Latin Americans are near European-Americans in European range.
