Sex reversal: a fountain of youth for sex chromosomes?

Evolution; international journal of organic evolution - 1 Dec 2009

Perrin Nicolas

Abstract excerpt

Nonrecombining Y chromosomes are expected to degenerate through the progressive accumulation of deleterious mutations. In lower vertebrates, however, most species display homomorphic sex chromosomes. To address this, paradox I propose a role for sex reversal, which occasionally occurs in ectotherms due to the general dependence of physiological processes on temperature. Because sex-specific recombination patterns...
