Sex-ratio drive in Drosophila simulans: variation in segregation ratio of X chromosomes from a natural population.

Abstract

The sex-ratio trait that exists in a dozen Drosophila species is a case of naturally occurring X chromosome drive that causes males to produce female-biased progeny. Autosomal and Y polymorphism for suppressors are known to cause variation in drive expression, but the X chromosome polymorphism has never been thoroughly investigated. We characterized 41 X… (More)
