青海本地黄牛乳中发现α_(s1)-CN^D等位基因

α_(s1)-CN^D Allele Discovered in Milk of Qinghai Native Cattle

采用聚丙烯酰胺凝胶电泳法对６４头青海本地黄牛乳汁中αｓ１－酪蛋白（αｓ１－ＣＮ）进行分析时，发现αｓ１－ＣＮＤ等位基因。它以杂合子形式存在，基因频率为０．０１５６．

Qinghai native cattle were used to analyse the α s1 casein (α s1 CN) in the milk by means of polyacrylamide gel electrophoresis.The results showed that a α s1 CN D allele was discovered in the milk of them. It presented in heterozygote. The frequency of the allele was 0.0156.
