Parental assignment in fish using microsatellite genetic markers with finite numbers of parents and offspring
Deterministic predictions for the proportion of offspring assigned to different numbers of parent-pairs are developed in order to investigate the power of microsatellite loci for parental assignment in fish species. Comparisons with stochastic simulation results show that predictions based on exclus...
