References Baras E This suggests that proto-sex chromosome size, intensity of selection for sexual dimorphism and intrinsic recombination rates would all be important parameters determining whether sex chromosomes undergo slow stepwise evolution, or rapid nonlinear divergence. Two of them, selection and migration differences among sexes, are commonly observed in nature and occur in the barbel hybrid zone, in the very direction required to explain our data.

Males and females are not separate genealogical entities at the scale of several generations: their autosomal genes are mixed at each generation.
