The indirect genetic effects of fathers on the expression and evolution of female reproductive traits in the wild is not well understood. In a wild population of great tits ( Parus major ), Evans et al. estimated the genetic and nongenetic effects of male mates on two female reproductive traits, lay date and clutch size. The estimated heritability of lay date (but not of clutch size) was increased by 1.5 times after accounting for male indirect genetic effects. This finding illustrates the importance of considering the effects of social partners in classic quantitative genetic models.
