Web7 de jul. de 2013 · 1. Introduction. The rate of evolution measures how quickly new traits can be established in a population. Typically, this is a function of three factors: mutation rate, population size and the fixation probability of new mutations [1–3], but there is increasing recognition that ecological influences, such as population structure [4,5] and the number … WebNatural selection acts on an organism’s phenotype, or observable features.Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries).When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the …
