A cryptic heterogametic transition revealed by sex-linked DNA markers in Palearctic green toads.

Journal of evolutionary biology - 1 May 2011

Stöck M, Croll D, Dumas Z, Biollay S, Wang J, Perrin N

Abstract excerpt

In sharp contrast to birds and mammals, most cold-blooded vertebrates have homomorphic (morphologically undifferentiated) sex chromosomes. This might result either from recurrent X-Y recombination (occurring e.g. during occasional events of sex reversal) or from frequent turnovers (during which sex-determining genes are overthrown by new autosomal mutations). Evidence for turnovers is indeed mounting in fish, but...
