| 摘 要： | 从宏观上看,基因的分离重组类似于分子的运动,都是自发地从有序走向无序、从集中走向分散。分离重组过程是一个熵增过程。本文运用物理学中熵的计算公式分别演算出在不同遗传机制的支配下遗传群体的熵值,发现显隐关系、分离规律、连锁等基因的行为规则及外界对生物的选择作用均能抑制群体的熵增。得出一对杂合等位基因从F1到Fn的基因型熵值变化规律。

| Abstract: | In macroscopic view, the segregation and recombination of genes is similar with the molecule movement, which is from order to out-of-order automatically and from concentration to scatteration. It is a process of entropy increment. Using the physics formula of entropy, we calculated separately entropy values in genetic population under governance on difference genetic mechanism. The conclusion of this study is that both of gene behaviors, such as dominance-recessive relation, segregation law, linkage, and environment selection on organisms can reduce entropy increment in the population. The law is got about entropy which changes from F1 to Fn. |
