摘　　要：本研究以野生鹌鹑和家鹑两个群体中的四个多型中性结构基因:乙醇脱氢酶(Adh)、酯酶-D(Es-D)、α-乙二醇磷酸脱氢酶(α-Gpd)和酯酶(Es)进行遗传共适应研究。结果表明:①在野生鹌鹑群体中,遗传共适应系数占遗传不平衡系数的42.9%～79.6%;在家鹑群体中,遗传共适应系数占遗传不平衡系数的35.7%～99.4%;②在家鹑群体中,α-Gpd-Es两位点之间的遗传共适应起着与连锁不平衡相反的作用;③起源于野生鹌鹑的家鹑与野生鹌鹑已经产生了一定的遗传分化;④遗传共适应是影响中性结构基因遗传不平衡的一个重要因素。Genetic coadaptability of four loci (Adh,Es-D,α-Gpd,Es)was studied in wild quail and domestic quail populations.The results were as follows:①In wild quail population,genetic coadaptability coefficient accounted for 42.9%～79.6%;In domestic quail population,the ratio was 35.7%～99.4%;②The effect of genetic coadaptabiliy and linkage disequilibrium was opposite between α-Gpd and Es loci in domestic quail population;③There was genetic initiation differentiation between wild quail and domestic quail originated from wild quail;④Genetic coadaptability was one of the key factors to the genetic disequilibrium of neutral loci.
