摘要
根据犏牛雄性不育的研究结果,提出了犏牛雄性不育的多基因遗传不平衡假说.假说认为,不育性是受多基因控制的,牦牛和普通牛由于在多个基因位点上的遗传差异而使犏牛的基因平衡失调,导致不育.
The polygenic inheritance unbalance hypothesis about male sterility of yak cattle is suggested on the base of the research results about male sterility of yak cattle.Sterility is controlled by polygenes.The genetic difference between the yak and ordinary cattle in polygene loci results in the gene unbalance of male yak cattle and male sterility.And part of the evidence of the hypothesis is discussed and analysed.
