Understanding the maintenance of genetic variation in the face of selection remains a key issue in evolutionary biology. One
potential mechanism for the maintenance of genetic variation is opposing selection during the diploid and haploid stages of
biphasic life cycles universal among eukaryotic sexual organisms. If haploid and diploid gene expression both occur, selection can
