| 摘 要： | 选取了8个微卫星位点对甘肃滩羊群体遗传多样性进行检测,计算了等位基因频率、有效等位基因数、群体杂合度和多态信息含量.结果表明:位点OarFCB128的有效等位基因数、群体杂合度和多态信息含量最高(Ne=10.26,H=0.902,PIC=0.885);位点MCM38的有效等位基因数、群体杂合度和多态信息含量最低(Ne=6.18,H=0.838,PIC=0.809);8个微卫星位点在滩羊群体中多态性丰富.表明滩羊群体的遗传杂合度较高,遗传多样性丰富,所选微卫星位点可用于滩羊遗传多样性评估. |

| Abstract: | Eight microsatellite loci were selected to analyze the genetic diversity of tan sheep.The allelie frequency,the effective number of allele(Ne),heterozygosity(H)and polymorphisms information content(PIC)were calculated at all mierosatellite loci.The results indicated that the Ne,H and PIC in the locus OarFCB128 were the highest(Ne=10.26,H=0.902,PIC=0.885);the Ne,H,PIC in the locus MCM38 were the lowest(Ne=6.18,H=0.838,PIC=0.809);the polymorphism of eight microsatellite loci in tan sheep was rich.Therefore,genetic heterozygosity of tan sheep was high,genetic diversity was rich.The selected microsatellite loci can be used to evaluate genetic diversity of tan sheep. |
