[Frequencies of mutant genes in two populations of domestic cats in southern Sakhalin].

Analyses of mutant gene frequencies have been completed for the domestic cat populations of cities Kholmsk and Juzhno-Sakhalinsk (Sakhalin isles). Mutant allele frequencies reported here differ from these of other Soviet Union populations of the tb and d loci. It is suggested that Sakhalin populations were influenced by domestic cat populations from East Asia. The genetic profile of the domestic cat of Sakhalin shows the close relationship with China populations. Furthermore, the results of the present study are very similar to those previously reported for Vladivostok and Khabarovsk. These similarity, perhaps, may be depend on their settlement history.
