[Mitochondrial DNA variation in Asian guardian dogs].
The hypervariable site of the mitochondrial DNA (mtDNA) control region has been studied in several sheepdog breeds. The genetic diversity is high in the Central Asian guardian dog and the Northern Caucasian wolf dog (an aboriginal group of breeds) and low in the Caucasian guardian dog. Haplotypes of groups A, B, C, and E/W have been found in Central Asian guardian dogs; haplotypes of groups A and B, in Caucasian guardian dogs. There is evidence suggesting a gene flow from Scandinavian dog populations to the Northern Caucasus. The results of the analysis allow the Caucasian guardian dog, Northern Caucasian wolf dog, Central Asian guardian dog, and the Turkish breeds akbash and kangal to be combined into a single group with an extremely low degree of differentiation.
