For example , if a population has just been formed by mixing two homozygous stocks AABB and A'A'B'B ' in equal numbers , the gene frequencies P1 , P2 , 91 , and q2 all equal 1/2 , but only two kinds of gametes are formed , AB and A'B ' ...

Here the curves represent gene frequency values of equal fitness . There is a peak at H , toward which the population moves by natural selection ; minimal values of W are at the points L. ( even if it is higher ) because it would have ...

The neutralist school points out that an entirely neutral mutation has a probability of 1 / 2N of being fixed in a population of effective size N ; the rate at which such mutations are fixed is equal to the mutation rate u .
