杂合子长期变化的计算机模拟试验——群体中长期保存杂合子的可能性分析

A computer Simulated Test for the Long-Time Change of Heterozygote Analysis of Possibility on Preserving the Heterozygote for Long-Time in Population

本文运用计算机模拟的方法,在随机交配、随机留种的情况下,分析了群体中长期保存杂合子的可能性。从模拟试验结果验证了群体遗传学理论的一个重要结论:群体中长期保存杂合子是不可能的。因此在畜禽保种工作中以减少基因纯合而保存群体全部基因为目的,来控制近交是不一定必要的。

Under the conditions of random mating and selecting. The research by computer simulation analysed the possibility of long-time conserving heterozygote in colong. An important conclusion was obtained. It was impossible to conserve heterozygote for a long time in colong. Therefore it is not necessary to control inbreeding for conserving all genes of colong by reducing gene purity in the work of conserving breeds for farm animal and poultry.
