Genetic co-adaptability among structural genes under the condition of genetic disequilibrium;
群体遗传不平衡条件下的遗传共适应现象及其遗传分析
43%) are genetic disequilibrium,6 of 18 sites combinations in different chromosomes are genetic disequilibrium for genetic co-adaptability.
本研究对吉林、黑龙江、辽宁3省的东北野猪群体随机采样42个,利用PCR-SSCP和PCR-RFLP技术检测到Nanog、瘦蛋白、胰岛素样生长因子蛋白3、JAK2、肠毒素大肠杆菌受体、心脏脂肪酸结合蛋白、钙蛋白酶抑制蛋白7个具有多态性的基因位点,并进行了群体遗传共适应性分析,结果表明:①7个多态性基因位点中有5个处于遗传不平衡状态,占所检测多态性基因位点的71。
The results were as follows: Genetic coadaptability was one of the key factors to the genetic disequilibrium in the population and reflecting important information of evolutionary history.
结果表明 :遗传共适应是影响群体遗传不平衡的重要原因之一 ,反映了群体进化历程中的重要信息 ,适用于种群系统分化、遗传结构评价和亲缘关系的研究。
