Полиморфизм гена рецептора меланокортина MC4R и его влияние на мясные и откормочные качества свиней

The study of G^A polymorphism in position 1426 of melanocortin receptor gene MC4R leading to the amino acid substitution Asp298Asn was carried out. The analysis was performed on 33 pig populations of different breed and origin (n=2072): Large White (9 populations), Landrace (8 populations), Duroc (4 populations), Yorkshire, Pietreain, Edelschwein, Livenskaja, Body, six different types of crosses and wild pig. The polymorphism of MC4R was detected using PCR RFLP analysis. The breed specific character of allele frequencies of MC4R gene was observed. The allele A frequency is varied of 6.7 per cent in Pietrain to 93.3 per cent in French Large White pigs. The higher frequency of allele A in Large White pigs (75.8±6.5 per cent) comparing to Landrace (34.4±5.7%, p
