Twelve polymorphic microsatellite DNA loci were isolated from genomic guppy DNA. We assessed the level of genetic diversity for these loci using individuals from five native Trinidadian populations. All the loci were polymorphic although there were considerable differences among loci and populations in allele frequencies. Within populations, the number of alleles ranged from 1 to 22 and observed heterozygosities ranged from 0.000 to 0.990. Allele frequencies differed substantially between populations suggesting divergence.
