First gene linked to temperature sex switch [Phys]

par Frédéric Magné - publié le

The sex of many reptile species is set by temperature. New research reported in the journal Genetics identifies the first gene associated with temperature-dependent sex determination in any reptile. Variation at this gene in snapping turtles contributes to geographic differences in the way sex ratio is influenced by temperature. Understanding the genetics of sex determination could help predict how reptiles will evolve in response to climate change.
