摘要
通过对柴达木黄牛和青海东部黄牛 ＨＢ，ＫＥ，ＴＦ，ＰＴＦ，ＰＡ，ＡＭＹＩ，ＡＬＰ Ａ，ＡＬＰ Ｂ，ＲＢＣ－ＬＤＨ１，Ｓ－ＬＤＨ １，α－ＬＡ，β－ＬＧ，αｓ１－ＣＮ和β－ＣＮ １４个生化遗传基因座多态性的分析，研究青海本地黄牛的遗传变异性及两个群体间的基因分化。结果发现：（１）青海本地黄牛１４个生化遗传基因座的Ｐｐｏｌｙ为８５．７％，Ｈ为０．２６６２，Ｎｅ为１．４８６１个，Ｈ．Ｉ．为０．５７９８；（２）柴达木黄牛与青海东部黄牛两群体之间的遗传距离为０．００５８，基因分化系数为０．００７１，表明青海本地黄牛两群体间的基因分化程度极小。
Both subpopulations of Chaidamu and Qinghai east yellow cattle were used to study the genetic variability and the gene differentiation between subpopulations for Qinghai native yellow cattle on the basis of analysis of polymorphism on fourteen biochemical genetic loci including HB , KE , TF, PTF, PA, AMYI, ALP A, ALP B, RBC-LDH1 S-LDH1, α-LA, β-LG, αs1-CN and β-CN.The results were as follows: (1)Ppoly,H,Ne and H. I. were 85 .7%,0.2622, 1 .4861 and 0. 5798, resp, on fourteen biochemical genetic loci for Qinghai native yellow cattle. (2) The genetic distance and Gst between Chaidamu and Qinghai east yellow cattle were 0. 0058 and 0. 0071, resp, showing a very small gene differentiation degree between both subpopulations of Qinghai native yellow cattle.
