Microsatellites are one of the most important classes of nuclear genetic markers and offer many advantages for the study of marine mammals. Here we describe the isolation and characterization of 12 cetacean microsatellites which are then tested across 30 different cetacean species. For around half the species tested, five or more polymorphic loci were identified. Since many species were represented by only one or two specimens, this figure is likely to underestimate the usefulness of these markers. No relationship was found between microsatellite repeat length and proportion of species which gave polymorphic products.
微卫星是核基因标记中最重要的类别之一，为海洋哺乳动物的研究提供了许多优势。在此，我们描述了12个鲸类微卫星的分离和特征分析，然后在30个不同的鲸类物种中进行了测试。在大约一半的测试物种中，鉴定出了五个或更多的多态性位点。由于许多物种仅由一两个样本代表，这个数字可能低估了这些标记的实用性。未发现微卫星重复长度与产生多态性产物的物种比例之间存在关系。
