Climate change, sex reversal and lability of sex-determining systems.

Abstract excerpt

Sex reversal at high temperatures during embryonic development (e.g., ZZ females) provides the opportunity for new genotypic crosses (e.g., ZZ male × ZZ female). This raises the alarming possibility that climatic warming could lead to the loss of an entire chromosome-one member of the sex chromosome pair (the Y or W)-and the transition of populations to environmental sex determination (ESD). Here we examine the...
