摘要
在ｓｈａｎｎｏｎ信息量的基础上，建立了相对纯合度信息量Ｓ′Ｊ（Ａ２）、相对杂合度信息量Ｓ′Ｈ（Ａ２）和相对信息量Ｓ′（Ａ２）的概念，并赋予它们以遗传学意义。与纯合度Ｊ和杂合度Ｈ进行了理论比较，结果表明，二者在数量规律性上有很好的一致性，而各相对信息量有更好的性质。１－Ｓ′Ｈ主要反映基因的确定度，Ｓ′Ｈ（Ａ２）主要反映基因的变异度；Ｓ′（Ａ２）与Ｋ无关，它能反映群体的遗传变异程度，亦能比较不同位点间的遗传变异程度。
Based on Shannon information theory,the relative information capacity of homozygosity S ′ J(A 2 ) and heterozygosity S ′ H(A 2 ),relative information capacity S ′(A 2 ) were set up,also meanings in genetics given to them,then theorical comparison with homozygosity J and heterozygosity H made.The results showed that they had very good uniformity in numerical regularity,each relative information capacity had better character.The S ′ J(A 2 ) mainly reflects gene identity and the S ′ H(A 2 ) mainly reflected gene diversity; S ′(A 2 ) had no relation to K ,which could reflect the genetic variation degrees of population,and also could distinguish the genetic variation degrees among different loci.
