Physiological sex predicts hybrid sterility regardless of genotype.

Science (New York, N.Y.) - 4 Jan 2008

Malone John H, Michalak P

Abstract excerpt

Reproductive isolation between biological species is characterized by Haldane's rule, which states that the heterogametic sex (XY or ZW) suffers the most dysfunctional effects of hybridization. It has been hypothesized that, in addition to X-linked recessive genes, Haldane's rule also reflects th...
