The genetic diversity of the red squirrel from Western Ukraine was estimated using 13 SSR loci. All of the loci found to be high polymorphic with allele number from five to 12. All coat colored groups of squirrel were insignificantly different by the allelic content of SSR loci. The private alleles were revealed with low frequency. The mean value of the expected heterozygosity was close at all of the investigating groups: 0,682 for red, 0,684 for black and 0,658 for dark-brown colored squirrels. The interpopulation genetic differentiation (FST) of squirrels with different coat color depends on the geographical component and equals 0,039. The obtained data assumes the absence of reproduction isolation and constant gene flow among red, black and dark-brown colored forms of S. vulgaris at Western part of Ukraine.
