One interpretation of these results is that there is strong evidence for an unequal female and male Ne in at least three of our six populations, with estimates of the breeding sex ratio (i.e., the effective size of females to males) ranging from 2.1 in the San to 12.5 in the Basque.Figure 2 shows Nx/Na is higher in Basques than in any of the sampled African populations (Mandenka, Biaka, and San).

Breeding sex ratio higher in Europe than sub-Saharan Africa
Another blow to Peter Frost's goofy-ass theories.
