So, you will grow by 60 bunnies per year and then you would shrink by the 15 that died. So, it would shrink by 15 bunnies, bunnies per year and so in ... WebWe can divide the number of copies of each allele by the total number of copies to get the allele frequency. By convention, when there are just two alleles for a gene in a population, their frequencies are given the symbols p p and q q: p = \text {frequency of}\: W p = frequency ofW = = 13/18 13/18 = = 0.72 0.72, or 72\% 72%.

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". [4] History [ edit] The theorem was first formulated in Fisher's 1930 book The Genetical Theory of Natural Selection.
