T. Yi et S. Lessard, Fundamental theorem of natural selection and frequency-dependent selection: Analysis of the matrix game diploid model, J THEOR BIO, 206(1), 2000, pp. 17-25
Following Ewens' interpretation about Fisher's fundamental theorem of natur
al selection, the matrix game model for diploid populations undergoing non-
overlapping, discrete generations is investigated. The total genetic varian
ce is decomposed and it is shown that the partial change in the mean fitnes
s, which is equal to the additive genetic variance over the mean fitness, c
an be thought of as a change due only to the partial changes in the phenoty
pic frequencies. (C) 2000 Academic Press.
