Polymorphism of stearoyl-CoA desaturase (SCD) gene in Hereford cattle breed

In this study, Stearoyl CoA Desaturase (SCD) gene polymorphism was determined in Hereford cattle breed. A702G, T762C and C878T single nükleotid polymorfphisms (SNPs) have been identified based on DNA sequence information of exon V region in SCD gene. AA, AG and GG genotype frequencies were 20.69%, 44.83% and 34.45% in A702G region, and TT, TC and CC genotype frequencies were 13.79%, 62.07% and 24.14% T762C region, and CC, CT and TT genotype frequencies were %44.83, 31.03 and 24.14 in C878T region, respectively. In addition, A and G allele frequencies were 0.431 and 0.569 in A702G region, T and C allele frequencies were 0.448 and 0.552 in T762C region, and C and T allele frequencies were 0.603 and 0.397 in C878T region, respectively. In addition, it was found that the population was not at Hardy-Weinberg equilibrium in terms of related SNP genotypes
