Faster-Z evolution is predominantly due to genetic drift.

Molecular biology and evolution - 1 Mar 2010

Mank Judith E, Nam Kiwoong, Ellegren Hans

Abstract excerpt

Genes linked to sex chromosomes may show different levels of functional change than autosomal genes due to different evolutionary pressures. We used whole-genome data from zebra finch-chicken orthologs to test for Faster-Z evolution, finding that Z-linked genes evolve up to 50% more rapidly than autosomal genes. We combined these divergence data with information about sex-specific expression patterns in order to...
