| 摘 要： | 在秦川牛品种中，Ｙ染色体具有多态性，即中或亚中及近端着丝点Ｙ染色体。对不同类型Ｙ染色体公牛的精液品质，体尺及外貌特征进行了统计分析。结果表明，Ｙ染色体多态性与精液品质，体尺及外貌特征不存在一定的相关关系。并对其意义和原因进行了讨论。

| Abstract: | There are Y chrotnosome polymorphism namely meta-or submeta -and acrocentric Y chromosomes within Qinchuan cattle breed. The sperm quality,body size and appear-ance of Qinchuan breeding bull with different Y chromosome were analysed statistically.The results showed that there is no definite relattonship existed between Y chromosome polymorphism and sperm quality,body size and appearance. The significance and cause of the results have been discussed. |
