In some species, females choose mates possessing ornaments that predict offspring survival. However, sexual selection by female preference for male genetic quality remains controversial because conventional genetic mechanisms maintain insufficient variation in male quality to account for costly preference and ornament evolution. Here we show that females prefer ornaments that indicate genetic quality generated by transmission conflict between the sex chromosomes. By comparing sex-ratio… CONTINUE READING
