摘要
本试验检测了杜泊羊群体中三个微卫星位点OarAE101、BMS2508和HH55的多态分布情况,结果表明:这三个位点都具有7个等位基因,其多态信息含量(PIC)、有效等位基因数(E)及群体杂合度(H)依次为OarAE101:0．8400/6．6370/0．8493;BMS2508:0．8218/5． 9620/0．8323;HH55:0．7875/5．0216/0．8009,具有较高的多态性,从而为杜泊羊群体遗传多样性的度量、品种间配合力的测定以及分子辅助选择提供重要的理论依据。
Gene frenquency, polymorphism information contents, number of effective allelles and heterozygosity were analysed in Dorper sheep by three microsatellite markers： OarAF.101, BMS2508 and HH55. The results sheued the three microsatellite markers all have seven alleles. The PIC, E and H of them were OarAE101： 0. 8400/6. 6370/0. 8493; BMS2508. 0. 8218/5. 9620/0. 8323; HH55： 0. 7875/5. 0216/0. 8009. It indicated that there are higher genetic polymorphisms at the three microsatellite markers. And all the three can be used for genetic polymophism evaluation in Dorper sheep breeds.
