An elementary proof of the fundamental theorem of natural selection in the case of two alleles
Consider a population which is ideal up to selective influences, and consider a locus with two alleles and let \(p\) and \(p'\) denote the gene frequency vectors corresponding to two consecutive generations. An elementary proof is given for the fact that the mean fitness of the population strictly increases along the straight line from \(p\) to \(p'\).
