The probability of having at least one ancestor from a source population in a specified generation. Considering the means among accepted parameter sets, $(s_{1,0},s_{1,1},\dots ,s_{1,13})=(1,0.896,0.783,0.779,0.713,0.490,0.129,0.061,0.061,0.061,0.085,0.085,0.085,0.085)$, $(h_0,h_1,\dots ,h_{13})=(0,0.015,0.127,0.132,0.198,0.421,0.781,0.902,0.902,0.902,0.899,0.899,0.899,0.899)$, and $(s_{2,0},s_{2,1},\dots ,s_{2,13})=(0,0.089,0.089,0.089,0.089,0.089,0.089,0.037,0.037,0.037,0.016,0.016,0.016,0.016)$ (Tables 1 and 2), the generation-specific probabilities of at least one African ancestor and at least one European ancestor are computed from equation (13).
