| 摘 要： | 目的]研究海门山羊群体3个基因位点遗传多态性与生长性状的关系,为提高海门山羊的生长性能以及培育快长型海门山羊新品系提供参考。方法]采用PCR-RFLP和PCR-SSCP技术对不海门山羊群体3个基因位点进行分析,并进行相关统计分析。结果]结果表明,在海门山羊群体中,海门山羊MSTN基因内含子Ⅱ、GH基因外显子Ⅰ和GH基因外显子Ⅱ均检测到2种基因型。这些位点不同的基因型对海门山羊的相关生长性状有着不同的影响。结论]该研究结果对通过标记辅助选择提高海门山羊体重等生长性状具有重要意义。

| Abstract: | Objective] The paper aims to study the relationship between genetic polymorphisms of three gene loci and growth character of Haimen Goats to provide reference to promote Haimen Goat growth character and cultivate Haimen Goat new strain of fast-growth.Method] We processed analysis and related statistical analysis on three gene loci of Haimen Goats with PCR-RFLP and PCR-SSCP.Result] The results suggested that there were two genotypes in MSTN gene IntronⅡ,GH gene exonⅠ and GH gene exonⅡ in Haimen Goats.Different genotypes of these gene loci had different effects on relative growth character of Haimen Goats.Conclusion] This study had a significant meaning about promoting Haimen Goat avoirdupois by marker assistant option. |
