摘要
应用遗传学原理对辖曼种羊场72头牦牛角性状的遗传方式进行了分析。初步结果表明,群体中有角和无角牦牛分别占44.44%和55.56%;牦牛角性状受常染色体上一对等位基因的控制,无角基因P对有角基因p为显性,但不完全,无角基因P的表现受其它修饰基因和激素水平的影响。
Heredity model of horn with 72 yak in Xiaman Farm was researched in the light of genetic principle. Preliminary result indcated that the horn and the hornless of yaks constituted 44.44 and 55.56% respectively. Horn trait was controlled by a couple of allele in autosome. The hornless dominated partially the horn and was effected by other modifiers and hormones.
