Genetic polymorphism of Holstein bulls of JVC ‘Krasnoyarskagroplem’ based on microsatellite DNA markers

The data on Holstein bulls (n = 24) were ana- lyzed by 12 microsatellite loci (according to Interna- tional ISAG Nomenclature) owned by JVC ‘Krasnoyarskagroplem’. 5 alleles of 67 had a fre- quency of more than 55 %: BM1 818266 (56 %), BM1824188 (60 %), ETH10219 (60 %),SPS115248 (77 %), TGLA126117 (70 %) in bulls. 7alleles were also identified to be found in 30-40 % of animals: BM2113125 (33 %), ETH3117 (42 %), ETH3129 (38 %), ETH225148 (33 %), ETH225150 (31%), INRA23210 (44 %), TGLA122143 (38 %). 2% ofthe bulls possessed the following alleles:BM2113137, ETH10213, ETH225146, SPS115260, TGLA53162, 178, 184, TGLA122159, 161, 171, TGLA22781.The number of alleles (Na) in the TGLA 126 locus was an average of 5.58 alleles per locus. Quantita- tively the degree of polymorphism was identified using two indicators -the level of heterozygosity (H) and the information of polymorphism index (PIC). According to the data of 12 microsatellite loci stud- ied in 24 manufacturing bulls, the heterozygosity values of the observed (Ho) and expected (He) var- ied between 0...
