Genetic Structure of the Population of HolsteinBlack-and-White Cattle by Microsatellite Loci
This article presents the results of a study of the genetic structure of a cattle population at 12 microsatellite loci. The object of the study was 702 specimens of cattle of Holstein black-motley breed. It was found that on average the heterozygosity of animals at the loci is 78.3%. The average number of alleles per locus is 7.0 ± 0.08. The most widespread in the population was the 248 bp allele, locus SPS115 – 0.644. Genotype 248/248 of the SPS115 locus has the highest frequency of occurrence – 0.446. 169 rare genotypes with a frequency of occurrence of less than 0.01 were identified in the population.
