Ronald Fisher first defined reproductive value in his 1930 book ''The Genetical Theory of Natural Selection'' where he proposed that future offspring be discounted at the rate of growth of the population; this implies that sexually reproductive value measures the contribution of an individual of a given age to the future growth of the population.〔(A theory of Fisher's reproductive value Published by PubMed.gov )〕〔(The Relation Between Reproductive Value and Genetic Contribution Published by the Genetics journal )〕 ==Definition== Consider a species with a life history table with survival and reproductive parameters given by $\backslash ell\_x$ and $m\_x$, where : $\backslash ell\_x$ = probability of surviving from age 0 to age $x$ and : $m\_x$ = average number of offspring produced by an individual of age $x.$ In a population with a discrete set of age classes, Fisher's reproductive value is calculated as : $v\_x\; =\; \backslash sum\_^\; \backslash lambda^\; \backslash frac\}\; m\_$ where $\backslash lambda$ is the long-term population growth rate given by the dominant eigenvalue of the Leslie matrix. When age classes are continuous, : $v\_x\; =\; \backslash int\_^\; e^\; \backslash frac\}\; m\_\; dy$ where $r$ is the ''intrinsic rate of increase'' or ''Malthusian growth rate''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Reproductive value (population genetics)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
