Abstract

An analysis of 344 species of tetrapods (birds, mammals, reptiles and amphibians) shows that taxa in which the female is heterogametic tend to have a more male-biased sex ratio; the mechanisms driving the association are unclear, but sex-determination systems are likely to have important consequences for the social behaviour and demography of tetrapods.
