The effect of unequal migration rates on FST.

abstract：:The differences between DNA-sequences within a population are the basis to infer the ancestral relationship of the individuals. Within the classical infinitely many sites model, it is possible to estimate the mutation rate based on the site frequency spectrum, which is comprised by the numbers C1,…,Cn-1 where n is the...

I develop quantitative genetic models of a female trait and a male preference to show when such a male preference can evolve.
