Two-locus autosomal sex determination: on the evolutionary genetic stability of the even sex ratio.

Proceedings of the National Academy of Sciences of the United States of America - 1 Mar 1990

Liberman U, Feldman M W, Eshel I, Otto S P

Abstract excerpt

In two-locus models of sex determination, there are two kinds of interior (polymorphic) equilibria. One class has the even sex ratio, and the other has equal allele frequencies in the two sexes. Equilibria of the second class may exhibit linkage disequilibrium. The condition for external stability of these second-class equilibria to invasion by a new allele is that the appropriately averaged sex ratio near the...
