摘要: FSHR基因5’端(包括侧翼序列和第一外显子)的限制性内切酶TaqⅠ的PCR-RFLP标记研究发现,在秦川牛中双胎母牛的A基因频率(0.5500)和AA基因型频率(0.5000)分别高于单胎母牛的A基因频率(0.3500)和AA基因型频率(0.3000);在黑白花奶牛中双胎母牛的B基因频率(0.5937)和BB基因型频率(0.6875)均高于单胎母牛的B基因频率(0.5416)和BB基因型频率(0.4167),也就是FSHR基因的5’端的PCR-RFLP标记在一个品种内单胎母牛和双胎母牛之间有一定趋势,但两个品种的趋势不同。

Abstract: PCR-RFLP in FSHR gene 5’–flanking region with exon 1 digested by restriction endonuclease TaqⅠdemonstrated that the frequencies of allele A (0.5500) and genotype AA (0.5000) in twinning cows were higher than that of allele A (0.3500) and genotype AA (0.3000) in monovular cows for Qinchuan cattle, while The frequencies of allele B (0.5937) and genotype BB(0.6875) in twinning cows were higher than that of allele B (0.5416) and genotype BB (0.4167) in monovular cows for Holstein cattle.
