In animals of western interbreed type allele of B–system: b (0,169), GYE'Q' (0,202), D'G'O' (0,058), G'G'' (0,058), OJ'K'O' (0,054), Q' (0,045) and I2 (0,041) have the highest rate. Proximity of the rate of “Holstein–Frisian” allele GYE'Q' and OJ'K'O'  of Black–Spotted cows indicated interbreed type and Holstein breed is the result of a high level holsteinization of the Western Ukrainian populations. Allele BYA'G'P'Q' G'', GTYBDGQYB”, YDGO’, DGO’, GG” , Oare typical only Black – Spotted cattle in Western Ukraine and almost never occur in related Black – Spotted breed. The high frequency of allele b in animals of interbreed western type can be explained using sires of Estonian Black – Spotted breed whose frequency but this allele is the highest (0,263). Genetic distance between Western interbreed type, the Ukrainian Black – Spotted Dairy breed and related breeds Black – Spotted breed was: Holstein – 0,483, Western Ukraine – 0,641, Estonian – 0,661, Polish – 0,733, Russian – 0,748 and Lithuanian – 0,830. Herewith the most genetically similar animals were Western interbreed type and Holstein breed. Along with significant commonality of genetic Holstein Western type of Black – Spotted cattle Ukraine has many specific features that are its originality and further confirm the validity of its autonomous existence and improvement. The genes of blood groups reflect changes in the genome populations and cattle breeds and make it possible to determine the features of statics and dynamics of genetic variability.
