| 摘 要： | 研究了在遗传同型交配下的世代交替中,一对等位基因群体的基因型信息熵和配子间的互信息。结果表明:随世代交替,随机交配下的平衡群体的基因型信息熵逐代减少、配子间的互信息逐代增加。从信息学角度看,在遗传同型交配下群体的遗传多样性逐代减少,配子间的信息交流逐代增加。最后应用Matlab进行了模拟,验证了所推导结果的正确性。 |
| 关 键 词： | 遗传同型交配 信息熵 互信息 |

| Abstract: | The character of genotypes entropy and inter-zygotes'' interentropy of a pair alleles population in mating of homologous genotypes was studied.The results showed that genot ypes entropy increasingly fell,and inter-zygotes'' inter-entropy increasingly rose in mating of homologous genotypes.It showed that genetical diversity of population is falling,and that connect of inter-zygotes is becoming more and more at the course of change.Atlast,the coclusions were tested and verified by imitation of computer. |
| Keywords: | Mating of homologous genotypes Shannon entropy Inter-entropy |
