Web"The rate of increase in the mean fitness of any organism, at any time, that is ascribable to natural selection acting through changes in gene frequencies, is exactly equal to its genetic variance in fitness at that time".

WebApr 10, 2024 · (b) Fitness costs and benefits should similarly emerge naturally from the life-history model. In the upper part of panel b, we see fitness costs emerging via two distinct mechanisms: a reduction in the probability of survival and a reduction in fecundity at a specific time point. Time moves from left to right, as indicated by the blue arrows.

WebThe answer comes when we consider an individual's inclusive fitness, which is the sum of an individual's direct fitness, the number of offspring produced, and indirect fitness, the number of relatives (nieces and nephews) produced multiplied by the degree of relatedness of those individuals. Relatedness WebWe can divide the number of copies of each allele by the total number of copies to get the allele frequency.
