【摘要】 采用聚丙烯酰胺凝胶电泳对 16匹中国矮马血清中白蛋白 (ALB)、酯酶 (Es)、α1-B糖蛋白 (A1B)和维生素D结合蛋白 (GC)进行了检测。结果发现 :在 4个位点中 ,白蛋白 (ALB)和酯酶 (Es)位点呈现多态性 ,而α1-B糖蛋白 (A1B)、维生素D结合蛋白 (GC) 2个位点均呈现单态性。在白蛋白 (ALB)位点发现 3个基因型 ,即AA、AB和BB ,由等位基因ALBA 和ALBB 控制 ,其基因频率分别为 0 .312 5和 0 .6 875 ;在酯酶 (Es)位点发现 4个基因型 ,即FS、II、FF和FI,由等位基因EsS、EsI 和EsF 控制 ,其基因频率分别为 0 .1875 ,0 .2 812和 0 .5 313更多还原

【Abstract】 Serum samples from 16 Chinese miniature horses were analyzed by polyacrylamide gel electrophoresis(PAGE).Out of 4 loci, polymorphism was detected at the albumin (Al) and esterase (Es)loci, the other two loci: A1B and Gc were noted to be monomorphic.Three phenotypes AA, AB and BB were found in the albumin locus,which was controlled by 2 alleles, namely ALB A and ALB B, its gene frequencies were 0.3125 and 0.6875, respectively. Four phenotypes FF, II, FI and FS -on the esterase locus, which was controlled 3 alleles, namely Es S, Es I and Es F, its gene frequencies were 0.1875, 0.2812 and 0.5313, respectively.更多还原
