| 摘 要： | 采用牙鲆GHR基因5'端Promoter区的1个微卫星标记,对胶南和日照2个牙鲆养殖群体进行了群体遗传多样性的研究,并探索该基因多态性位点与牙鲆生长性状之间的相关性.结果表明,2个群体在该座位的等位基因数为12和9个,有效等位基因数为6.26和5.04个,多态信息含量为0.84和0.80.2个群体该座位的Hardy-Weinberg遗传偏离指数均为正值,并没有显示出杂合子缺失,但各基因型分布频率都在一定程度上偏离Hardy-Weinberg平衡(P<0.01).连锁分析中发现,在胶南群体中,IM基因型对应的个体在全重、全长、体长、头长、体高和眼径形态学数据中均是最大的;在日照群体中,BC基因型对应的个体在全重、全长、体高、尾柄高、尾柄长和眼径数据中均是最大的;而CJ基因型对应的个体在体长和头长这两组数据中是最大的.该结果为研究GHR基因的变异对鱼类生长发育的影响及探索将该基因作为生长遗传标记的可行性奠定了实验基础.

| Abstract: | Genetic diversity of two cultured stocks of the left eyed flounder(Paralichthys olivaceus) from Jiaonan Country and Rizhao Country were analysed by using one microsatellite loci in the 5' promoter region of growth hormone receptor(GHR)gene,and the polymorphisms and their associations with growth traits were also investigated.The results showed that the allele numbers were 12 and 9,respectively,the effective alleles numbers were 6.26 and 5.04,the Fixation Indexes were-0.02 and-0.20,the Shannon indexes were 2... |
