Indirect genetic effects increase heritability estimates for male and female extra-pair reproduction.

Evolution; international journal of organic evolution - 27 Jul 2023

Dobson Sarah, Dunning Jamie, Burke Terry, Chik Heung Ying Janet, Schroeder Julia

Abstract excerpt

The question of why females engage in extra-pair behaviors is long-standing in evolutionary biology. One suggestion is that these behaviors are maintained through pleiotropic effects on male extra-pair behaviors (genes controlling extra-pair reproduction are shared between sexes, but only beneficial to one sex, in this case, males). However, for this to evolve extra-pair reproduction must be both heritable and...
