Sex-Specific Dominance of Gene Expression in Seed Beetles.

ABSTRACT: When different alleles are favored in different environments, dominance reversal where alternate alleles are dominant in the environment in which they are favored can generate net balancing selection. The sexes represent two distinct genetic environments and sexually antagonistic (SA) selection can maintain genetic variation, especially when the alleles involved show sex-specific dominance. Sexual dimorphism in gene expression is pervasive and has been suggested to result from SA selection. Yet, whether gene-regulatory variation shows sex-specific dominance is poorly understood. We tested for sex-specific dominance in gene expression using three crosses between homozygous lines derived from a population of a seed beetle, where a previous study documented a signal of dominance reversal for
