Patterns of molecular evolution of an avian neo-sex chromosome.

Molecular biology and evolution - 1 Dec 2012

Pala Irene, Hasselquist Dennis, Bensch Staffan, Hansson Bengt

Abstract excerpt

Newer parts of sex chromosomes, neo-sex chromosomes, offer unique possibilities for studying gene degeneration and sequence evolution in response to loss of recombination and population size decrease. We have recently described a neo-sex chromosome system in Sylvioidea passerines that has resulted from a fusion between the first half (10 Mb) of chromosome 4a and the ancestral sex chromosomes. In this study, we...
