- Abstract
The local mate competition (LMC) theory showed that in isolated subpopulations, female-biased sex ratios evolve because sons of a parent tend to compete with each other. Further development of LMC theory showed that in-breeding in haplodiploid species causes mothers to share more genes with daughters than with sons, and this selects for even more female-biased sex ratios. Due to their natural history, wasps have been widely utilized for testing the prediction of LMC theories. In each generation, a small number of mated females oviposit in a syconium.
