Generation-specific genealogical and genetic ancestry features for African-Americans. a) Generationwise mean admixture contributions $s_1$ (African), h (African-American), and $s_2$ (European) across accepted parameter sets. Error bars show standard deviations. b) Means across accepted parameter sets of the expected numbers of African-American genealogical and genetic ancestors possessed by a random individual, as calculated by Eqs. 3 and 20. Error bars show the standard deviations of these expected numbers across accepted parameter sets. The values plotted in a) are obtained by summarizing the distributions underlying Fig. 4 of Mooney et al. (2023). The values in b) are given in Table 1.
