Abstract

The genetic polymorphism of the beta-lactoglobulin gene was investigated in 182 sheep of Turkish fat-tailed sheep breeds by using PCR-RFLP methods. In the study, two alleles (A and B) and three genotypes (AA, BB and AB) at beta-lactoglobulin locus were observed. The most common genotype at the beta-lactoglobulin locus was AB. The greatest frequency of allele A was detected in Tuj breed as 0.7188. Results of the present study show that genetic polymorphism exists in the Turkish fat-tailed sheep breed population used in this study.
β-laktoglobulin geninin genetik polimorfizmi Türkiye yağlı kuyruklu koyun ırklarının 182’sinde PCR-RFLP metodu kullanılarak incelenmiştir. Çalışmada, β-laktoglobulin lokusunun iki alleli (A ve B) ve üç genotipi (AA, AB ve BB) gözlenmiştir. β-laktoglobulin lokusundaki en yaygın genotip AB genotipidir. A allelinin en yüksek frekansı 0.7188 olarak Tuj ırkında belirlenmiştir. Mevcut çalışmanın sonuçları, kullanılan Türk yağlı kuyruklu koyun ırklarında genetik polimorfizmin varlığını göstermiştir.
