- Five new polymorphic microsatellite loci were developed for the coral reef damselfish Pomacentrus amboinensis. Twenty-four individuals from two Great Barrier Reef populations were genotyped at the five loci, with numbers of alleles per locus ranging from 6-23 and observed heterozygosity between 0.42-0.92. In addition, the cross-species testing of six primers developed for Stegastes partitus revealed one primer (SpGATA40) that was also polymorphic for P. amboinensis. Due to high levels of polymorphism (>=14 alleles) in at least four of the six loci and a high proportion of tetranucleotide repeats, these microsatellite markers should be useful for parentage assignment as well as other investigations of individual relatedness.
