This paper introduces the entropy of the genepool and the genetype of a pair alleles population in inbreeding , and demonstrates the character of genetype entropy , the character of inter - zygote ' s inter - entropy , and the relation between the latter and coefficient of inbreeding in the generation change 摘要研究了在近亲繁殖下一对等位基因群体的基因库信息熵和基因型信息熵,并讨论了在世代交替中基因型信息熵的性质、配子间的互信息性质及其与近交系数的关系,并定义了配子间的近交关联信息系数。
