Pronounced reproductive skew in a natural population of green swordtails, Xiphophorus helleri.

Molecular ecology - 1 Oct 2008

Abstract excerpt

For many species in nature, a sire's progeny may be distributed among a few or many dams. This poses logistical challenges--typically much greater across males than across females--for assessing means and variances in mating success (number of mates) and reproductive success (number of progeny). Here we overcome these difficulties by exhaustively analyzing a population of green swordtail fish (Xiphophorus...
