Abstract
<p>In an ancestral population with PXI, and segregating for a sexually antagonistic balanced polymorphism, unbiased RXI is favored and may evolve when <i>h</i><<i>h<sub>crit</sub></i> = (1−<i>t<sub>m</sub></i>)/(2−<i>t<sub>m</sub></i>). Following such an evolutionary transition, the male-beneficial/female-detrimental allele approaches a new equilibrium frequency, and mean fitness per sex evolves to a new equilibrium.</p
