摘  要:
本文对微卫星基因座BMS1248和MAF70在太行黑山羊中的遗传多样及其与生长性能的相关性进行研究。结果表明:2个微卫星座位在太行黑山羊中共检测到18个等位基因;平均多态信息含量(PIC)为0.824;平均有效等位基因和平均杂合度分别为7.746和0.869。微卫星基因座BMS1248在太行黑山羊中基因型123/123 bp可能与体重、体高、体长、胸围呈正相关。微卫星基因座MAF70在太行黑山羊中基因型155/155 bp可能与体重、基因型165/192 bp与体高呈正相关。研究推测在2个基因座上存在对相关生长性状具有正效应或负效应的等位基因。

摘  要:
Microsatellites BMS1248 and MAF70 were selected to detect the genetic polymorphism and their correlation to the growth performance in Taihang Black Goat.The results showed that 18 alleles were detected in total,and the average polymorphism information content(PIC) was 0.824,and average number of effective alleles(Ne) and average heterozygosity(h) was 7.746 and 0.869,respectively.The genotype 123/123 bp at BM1248 has positive effects on body weight,body length and heart girth.The genotype 155/155b at MAF70 has positive effects on body weight,and the genotype 165/192 bp has positive effect on height at withers.We concluded that some alleles detected loci has positive/negative effects on definite growth performance in the goats.
