When Sex Chromosomes Recombine Only in the Heterogametic Sex: Heterochiasmy and Heterogamety inHylaTree Frogs

5 Aug 2020

Abstract excerpt

Sex chromosomes are classically predicted to stop recombining in the heterogametic sex, thereby enforcing linkage between sex-determining (SD) and sex-antagonistic (SA) genes. With the same rationale, a pre-existing sex asymmetry in recombination is expected to affect the evolution of heterogamety, for example, a low rate of male recombination might favor transitions to XY systems, by generating immediate linkage...
