Positive selection near an inversion breakpoint on the neo-X chromosome of Drosophila americana.

Genetics - 1 Nov 2007

Evans Amy L, Mena Paulina A, McAllister Bryant F

Abstract excerpt

Unique features of heteromorphic sex chromosomes are produced as a consequence of sex-linked transmission. Alternative models concerning the evolution of sex chromosomes can be classified in terms of genetic drift or positive selection being the primary mechanism of divergence between this chromosomal pair. This study examines early changes on a newly acquired chromosomal arm of the X in Drosophila americana,...
