查询词典 prolificacy

The gonadotropin releasing hormone receptor gene was studied as a candidate gene for the prolificacy of Small Tail Han sheep. Eight pairs of primers were designed to detect single nucleotide polymorphisms of exon 1, exon 2 and exon 3 of GnRHR gene in both high fecundity breeds and low fecundity breeds (South African Mutton Merino, Corriedale and Chinese Merino sheep) by PCR-SSCP. Only the products amplified by primers P4 and P7 displayed polymorphisms.

The inhibin a gene、 the bone morphogenetic protein 4 (BMP4) gene and the bone morphogenetic protein 7 (BMP7) gene were studied as candidate genes on the prolificacy of Small Tail Han sheep. Single nucleotide polymorphisms of 5 ' regulatory region、 exon 1 of INHA gene;exon 2、 exon 3 and exon 4 of BMP4 gene and exon 2、 exon 3 of BMP7 were detected in high fecundity breed and low fecundity breeds (Chinese Merino sheep, Corriedale sheep and South African Mutton Merino sheep) by PCR-SSCP. The results indicated that there was a mutation (316C→T) in 5' region of INHA gene in Small Tail Han sheep, Chinese Merino sheep and Corriedale sheep, the same mutation did not exist in South African Mutton Merino sheep.

采用PCR-SSCP技术检测抑制素α(inhibin α，INHA)基因5'调控区、外显子1，骨形态发生蛋白4(bone morphogenetic protein 4，BMP4)基因外显子2、外显子3和外显子4以及骨形态发生蛋白7(bone morphogenetic protein 7，BMP7)基因外显子2和外显子3在高繁殖力绵羊品种以及低繁殖力绵羊品种(中国美利奴绵羊、考力代绵羊、南非肉用美利奴绵羊)中的单核苷酸多态性，同时研究这三个基因对小尾寒羊高繁殖力的影响。
