Abstract

Genotyping of the leptin gene locus (LEP) (SNP: R25C, Y7F, and A80V) has been conducted in cows from two cattle droves (n=106 and n=34) and in bulls of Ayrshire cattle (n=9) that are intensively used at present for artificial insemination in cows in Krasnodar krai. The absence of A80V polymorphism...
