    摘要研究了在近親繁殖下一對等位基因群體的基因庫信息熵和基因型信息熵，並討論了在世代交替中基因型信息熵的性質、配子間的互信息性質及其與近交系數的關系，並定義了配子間的近交關聯信息系數。
  15. Inbreeding increases homozygosity so that deleterious recessive genes are expressed more often in the phenotype, and decreases heterozygosity and hence the potential genetic varability of the population

    近親交配使純合體幾率增加，因此，一些有害的隱性基因可以被表達。
