Sex-biased gene expression at homomorphic sex chromosomes in emus and its implication for sex chromosome evolution.

Proceedings of the National Academy of Sciences of the United States of America - 16 Apr 2013

Vicoso Beatriz, Kaiser Vera B, Bachtrog Doris

Abstract excerpt

Sex chromosomes originate from autosomes. The accumulation of sexually antagonistic mutations on protosex chromosomes selects for a loss of recombination and sets in motion the evolutionary processes generating heteromorphic sex chromosomes. Recombination suppression and differentiation are generally viewed as the default path of sex chromosome evolution, and the occurrence of old, homomorphic sex chromosomes,...
