title: Microsatellite DNA markers indicate three genetic lineages in East Asian indigenous goat populations.
abstract: The genetic differentiation and phylogenetic relationships of 18 indigenous goat populations from seven East Asian countries were analysed based on data obtained from 26 microsatellite DNA markers. The mean number of alleles (MNA) per population ranged from 2.5 to 7.6, with an average of 5.8. Genetic variability estimated from MNA and heterozygosity (H(E) and H(O) ) were relatively low in coastal and island populations. A heterozygous deficiency within populations (F(IS) = 0.054, P < 0.001) and total inbreeding (F(IT) = 0.181, P < 0.01) were observed, and genetic differentiation in the populations (F(ST) ) was 13.4%. The results of Bayesian model-based clustering and a neighbour-joining tree based on Nei's genetic distance showed that Asian goat populations could be subdivided into at least the following three genetic clusters: East Asian, Southeast Asian and Mongolian. These results are in close accordance with conventional morphological and geographical classifications and migration history.
