Unisexual fish in the genus Poeciliopsis require males of sympatric bisexual species for insemination. Males tend to avoid mating with the unisexual hybrids, leaving a significant proportion unfertilized. This study demonstrates that males are more likely to mate with unisexuals of unfamiliar clones than with those of familiar clones. This unfamiliar-female advantage may translate into a rare-female advantage in nature, favoring uncommon clones and thereby contributing to the coexistence of numerous unisexual clones.
