A set of polymorphic dinucleotide and tetranucleotide microsatellite markers for the Indo-Pacific humpback dolphin (Sousa chinensis) and cross-amplification in other cetacean species

Eleven dinucleotide and five tetranucleotide polymorphic microsatellite loci were presented for the Indo-Pacific humpback dolphin Sousa chinensis, a species categorized as ‘data deficiency’ in the IUCN Red List. These markers were developed to allow future population studies, such as characterization of population structure and genetic diversity that are important for the species’ conservation. The number of alleles ranged from 2 to 9 with observed heterozygosity ranging from 0.167 to 0.917, and expected heterozygosity ranging from 0.159 to 0.913. Test of these loci in five additional cetacean species found that 10–13 loci have successful cross-amplifications.
