Sex-specific adaptation drives early sex chromosome evolution in Drosophila.

Science (New York, N.Y.) - 20 Jul 2012

Zhou Qi, Bachtrog Doris

Abstract excerpt

Most species' sex chromosomes are derived from ancient autosomes and show few signatures of their origins. We studied the sex chromosomes of Drosophila miranda, where a neo-Y chromosome originated only approximately 1 million years ago. Whole-genome and transcriptome analysis reveals massive degeneration of the neo-Y, that male-beneficial genes on the neo-Y are more likely to undergo accelerated protein...
