Non-recombining sex chromosomes are expected to accumulate deleterious mutations under the combined effects of Muller’s ratchet and Hill-Robertson effects, and for this reason to progressively degenerate. Such decay has been largely documented in birds and mammals, most of which have strongly heteromorphic sex chromosomes with degenerated W and Y, respectively. In sharp contrast, however, cold-blooded vertebrates rarely show such a differentiation, even when sex determination is purely genetic. The present project aims at investigating the evolutionary dynamics of non-degenerating sex chromosomes, using amphibians as model organisms.
