Sexual dimorphism in body size and the origin of sex-determination systems.

The American naturalist - 1 Apr 2014

Adkins-Regan Elizabeth, Reeve Hudson K

Abstract excerpt

Diverse sex-determining systems occur in vertebrates, including environmental sex determination (ESD), genetic sex determination (GSD) of type XX/XY (heterogametic males), and GSD of type ZZ/ZW (heterogametic females). The origins of the two genetic types are poorly understood. We use protected invasion theory to derive a model that generates testable predictions about the origins of the two genetic types from...
