Sex roles and sex ratios in animals

Biological Reviews, 2022
ABSTRACTIn species with separate sexes, females and males often differ in their morphology, physiology and behaviour. Such sex‐specific traits are functionally linked to variation in reproductive competition, mate choice and parental care, which have all been linked to sex roles.

The way these genes are regulated suggests new complexities in the sex determination pathway.
