Özet
Kivircik crossbred sheep in the Thrace region are commonly grown for meat production. The objective of the present study was to determine the polymorphism of insulin-like growth factor 1 (IGF1) and leptin (LEP) genes in Kivircik crossbred ewes. Therefore, IGF1/BfoI and Lep/BcnI polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism method. The single nucleotide polymorphism (SNP) in the regulatory region of the IGF1 gene was detected by amplification of the 294 bp region using specific primers and cleavage with the BfoI enzyme. Allele frequencies of A and B were found with 0.915 and 0.085 respectively. The genotype frequencies of IGF1 gene were 0.85 (AA), 0.13 (AB) and 0.02 (BB). The SNP in the exon 3 of the LEP gene was detected by amplification of the 494 bp region using specific primers and cleavage with the BcnI enzyme. The estimated frequencies of three genotypes including GG, GA and AA at Lep/BcnI polymorphism were 0.90, 0.09 and 0.01 and they were 0.055 and 0.945 for A and G alleles, respectively. LEP and IGF1 gene showed polymorphic patterns in Kivircik crossbred sheep population. There was no deviation from Hardy-Weinberg equilibrium (P>0.05) relative to LEP and IGF1 genotypes.
