| 摘 要： | 研究多基因座复等位基因的自交群体后代基因型频率,给出其递推算法,结果发现多个基因座都是纯合基因的基因型频率逐代增加,相对增加量逐代减少,最终趋于一个定值;而多个基因座中有杂合基因的基因型频率最终趋于0,但有可能前几代递增,以后逐代减少;杂合基因个数越多,趋于0的速度越快。

| Abstract: | This paper studies the offspring＇s genotype frequency of the selfing population on multiple alleles with limited loci.A recursive algorithm is given for it.It is discovered that the genotype frequency of homozygous gene of limited loci increases by generations.Relative increment reduces by generations and the genotype frequency tends to a definite value finally.The genotype frequency of limited loci with hybrid gene tends to 0 finally.But it is possibility that the genotype frequency increases in previous generations then reduces later.It is found that the number of the hybrid gene are more,the speeds tending to 0 are quicker. |
