Summary The genetic differentiation and phylogenetic relationships of 18 indigenous goat populations from seven E ast A sian 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.
