摘要
根据试验测定的结果对杂种优势产生的分子遗传机理进行了讨论,认为动物个体杂种优势的产生是由于杂种后代体内来自双亲的DNA分子之间发生了多位点的混杂,这种混杂导致杂种后代产生出与其亲本不同的性状表现,从而导致了杂种优势的产生。
The molecular genetic theory of heterosis was discussed according to the result of some related experiments.We thought that the animal heterosis was produced by the hybrid descendants' DNA confused in multiloci originating f rom both parents,which caused the traits different between the hybrid descenden ts and theiv parents,and this is also the heterosis.
