Microsatellite loci for paternity analysis in the fathead minnow,Pimephales promelas (Teleostei: Cyprinidae)

Many recent studies have employed molecular markers to uncover important aspects of mating systems in teleost fishes. The fathead minnow (Pimephales promelas) is a nest‐building North American cyprinid that spawns multiply and exhibits exclusive male parental care. A battery of microsatellite markers was developed to analyse paternity in this species. The seven characterized loci possess four to 31 alleles and expected heterozygosities of 0.455–0.974. In combination, they elicit an exclusion probability of 0.999, a desirable level for paternity analysis. In addition, cross‐amplifications were conducted to test primer efficacy in 13 other taxa, including two congeners.
