Abstract

The genetic polymorphism of the beta-lactoglobulin gene was investigated in three native Turkish sheep breeds. The study was carried out on 108 sheep (29 Kivircik, 38 Gökçeada, and 41 Sakiz) by means of PCR-RFLP methods. Two genetic variants (A and B) and three genotypes (AA, AB, and BB) of beta-lactoglobulin have been identified. The gene frequencies of beta-LG A and B were 0.7759 and 0.2241 in Kivircik, 0.7632 and 0.2368 in Gökçeada, and 0.9756 and 0.0244 in Sakiz breeds, respectively. The populations were in Hardy-Weinberg equilibrium in all samples from the three breeds.

摘要

对三个土耳其本土绵羊品种的β-乳球蛋白基因的遗传多态性进行了研究。通过聚合酶链反应-限制性片段长度多态性（PCR-RFLP）方法对108只绵羊（29只基尔维吉克羊、38只戈克恰达羊和41只萨基兹羊）进行了研究。已鉴定出β-乳球蛋白的两种遗传变体（A和B）和三种基因型（AA、AB和BB）。β-LG A和B的基因频率在基尔维吉克羊中分别为0.7759和0.2241，在戈克恰达羊中为0.7632和0.2368，在萨基兹羊品种中为0.9756和0.0244。这三个品种的所有样本群体均处于哈迪-温伯格平衡状态。
