| 摘 要： | 研究了随机交配群体中2对基因9种基因型在不同适合度下所占比例的逐代变化。发现只按1对基因统计时,在另1对基因的影响下,所考察基因3种基因型的适合度不再是常数。通过数据模拟可找出基因频率逐代变化的极限,模拟结果可解释生产中很难看到杂种劣势的原因。

| Abstract: | The generational change of the proportions of 9 kinds of genotypes that controlled by 2 pairs of gene in panmixis population at different fitness was studied.It was found that if only 1 pair of gene was calculated,the fitness of 3 kinds of genotypes that controlled by the investigated gene was no longer a constant under the effect of another pair of gene.But the generational change limit of gene frequency could be found through data simulation,and the simulation results could explain the reason why hybrid w... |
