摘  要:
本文采用PCR-RFLP技术,对560只黄羽肉公鸡的NPY基因3个酶切位点进行了多态性研究,并分析其与睾丸性状的关系。结果表明:rs3和rs19识别位点在隐性纯合子的情况下表现为较大的睾丸重(P<0.05)和睾丸指数,这两个位点可以作为睾丸性状的候选分子标记。

摘  要:
In this study,PCR-RFLP was used to investigate the polymorphisms at three locus of NPY gene in 560 yellow-feather male broilers and analyze their relationship with testis trait. The results showed that the recessive homozygous of both rs3 and rs19 locus were related to higher testis weight and testis index significantly (P<0.05). It was indicated that these two locus could be used as candidate molecular markers for testis trait.
