Abstract :This study was carried out to determine the genetic polymorphism of the β-lactoglobulin insert ignore into journalissuearticles values(β-Lg); gene for indigenous Kivircik breed in Turkey. As to find the Kivircik Sheep is limited as purebred, this breed was raised and maintained in special farm with small numbers as pure breeds. Due to animal material was constituted 48 heads as purebred Kivircik sheep. The study was realized by means of PCR-RFLP methods. Also, two genetic alleles insert ignore into journalissuearticles values(A and B); and three genotypes insert ignore into journalissuearticles values(AA, AB and BB); were detected for this purebred. The gene frequencies of β-Lg A and B were calculated as 0.469 and 0.531 in Kivircik sheep. The population was found in equilibrium according to Hardy-Weinberg. At the same time, Some F statistics values were calculated like effective alleles number insert ignore into journalissuearticles values(Ne);, observed heterozygosity insert ignore into journalissuearticles values(Ho);, expected heterozygosity insert ignore into journalissuearticles values(He); and fixation index insert ignore into journalissuearticles values(Fis);; 1.992, 0.396, 0.498 and 0.205, respectively.
