Evolutionary conservation of ten microsatellite loci in four species of Felidae

Short tandem repeat polymorphisms (STRP), or microsatellites, are widespread among vertebrate genomes and are useful in gene mapping and population studies due to a high level of length polymorphism. We describe here the isolation, characterization, and PCR amplification of 10 microsatellite loci from the domestic cat, Felis catus. The flanking primer sequences were conserved among other Felidae species, and amplification products demonstrated abundant polymorphism in puma, lion, cheetah, and domestic cat. The cheetah sample exhibited the lowest level of polymorphism for these loci among felid species.
