Cryptic recombination in the ever-young sex chromosomes of Hylid frogs.

Journal of evolutionary biology - 1 Oct 2012

Guerrero R F, Kirkpatrick M, Perrin N

Abstract excerpt

Sex chromosomes are expected to evolve suppressed recombination, which leads to degeneration of the Y and heteromorphism between the X and Y. Some sex chromosomes remain homomorphic, however, and the factors that prevent degeneration of the Y in these cases are not well understood. The homomorphic sex chromosomes of the European tree frogs (Hyla spp.) present an interesting paradox. Recombination in males has...
