(A) The relative amount of recessive allelic variation for fitness in males () and females () was significantly negatively correlated ( = −0.779 [95% CI −0.92 to −0.46], P = 0.0004) across strains (N = 16; units reflect nonstandardized residual fitness from a model that accounted for environmental and epistatic variance), and (B) the same relationship illustrated and analyzed as ranks (i.e., strains ranked in order of their relative “dominance” over one another; : −0.738, P = 0.0016). Strains tended to be enriched with allelic variation for fitness that was dominant in their heterozygous sons but recessive in their heterozygous daughters and vice versa. SSDR, sex-specific dominance reversal.
