Independent degeneration of W and Y sex chromosomes in frog Rana rugosa.

Chromosome research : an international journal on the molecular, supramolecular and evolutionary aspects of chromosome biology - 1 Jan 2012

Miura Ikuo, Ohtani Hiromi, Ogata Mitsuaki

Abstract excerpt

The frog Rana rugosa uniquely possesses two different sex-determining systems of XX/XY and ZZ/ZW, separately in the geographic populations. The sex chromosomes of both types share the same origin at chromosome 7, and the structural differences between X and Y or Z and W were evolved through two inversions. In order to ascertain the mechanisms of degeneration of W and Y chromosomes, we gynogenetically produced...
