The evolution of XY recombination: sexually antagonistic selection versus deleterious mutation load.

Evolution; international journal of organic evolution - 1 Oct 2012

Grossen Christine, Neuenschwander Samuel, Perrin Nicolas

Abstract excerpt

Recombination arrest between X and Y chromosomes, driven by sexually antagonistic genes, is expected to induce their progressive differentiation. However, in contrast to birds and mammals (which display the predicted pattern), most cold-blooded vertebrates have homomorphic sex chromosomes. Two main hypotheses have been proposed to account for this, namely high turnover rates of sex-determining systems and...
