    Abstract

    Strongylocentrotus sea urchins are common subjects for studies in developmental and cell biology, reproductive biology, ecology, and evolution. We report 14 microsatellite loci from the red urchin, S. franciscanus, isolated for the purpose of estimating paternal success of males in experimental group spawns. Most of these loci were found to be highly polymorphic in a population from British Columbia. A high frequency of null alleles appears responsible for heterozygote deficit at a majority of these loci, but if used with appropriate caution, these microsatellites should be effective markers for studies of Strongylocentrotus populations.
