Differential barrier strength and allele frequencies in hybrid zones maintained by sex-biased hybrid incompatibilities.

Heredity - 1 Mar 2008

Wang R-X, Zhao Y-L

Abstract excerpt

In animals, hybrid sterility and inviability between closely related species often affect only the heterogametic sex (XY). This widespread phenomenon, known as Haldane's rule, is an early speciation event found across broad taxa, but the role of heterogametic hybrid incompatibilities, as opposed to homogametic ones, as a barrier in a speciation process remains obscure. It has been hypothesized that heterogametic...
