Strong reproductive skew among males in the multiply mated swordtail Xiphophorus multilineatus (Teleostei).

The Journal of heredity - 1 Jan 2000

Luo J, Sanetra M, Schartl M, Meyer A

Abstract excerpt

Male swordtails in the genus Xiphophorus display a conspicuous ventral elongation of the caudal fin, the sword, which arose through sexual selection due to female preference. Females mate regularly and are able to store sperm for at least 6 months. If multiple mating is frequent, this would raise the intriguing question about the role of female choice and male-male competition in shaping the mating system of...
