Evolution of female choice under intralocus sexual conflict and genotype-by-environment interactions.

ABSTRACT: In many species, females are hypothesized to obtain 'good genes' for their offspring by mating with males in good condition. However, female preferences might deplete genetic variance and make choice redundant. Additionally, high-condition males sometimes produce low-fitness offspring, for example because of environmental turnover and gene-by-environment interactions (GEIs) for fitness, or because fit males carry sexually antagonistic alleles causing them to produce unfit daughters. Here, we extend previous theory by investigating the evolution of female mate choice in a spatially explicit evolutionary simulation implementing both GEIs and intralocus sexual conflict (IASC), under sex-specific hard or soft selection. We show that IASC can weaken female preferences for high-condition males o
