Evidence of a neo-sex chromosome in birds.

Heredity - 1 Mar 2012

Pala I, Naurin S, Stervander M, Hasselquist D, Bensch S, Hansson B

Abstract excerpt

Neo-sex chromosomes often originate from sex chromosome-autosome fusions and constitute an important basis for the study of gene degeneration and expression in a sex chromosomal context. Neo-sex chromosomes are known from many animal and plant lineages, but have not been reported in birds, a group in which genome organization seems particularly stable. Following indications of sex linkage and unexpected...
