Changes of Allele Frequency Under Natural Selection in Large Random Mating Populations

Conditions under which the problem can be simplified In earlier chapters we have shown that changes of allele frequency under drift are very slow; rather little change will take place if the number of generations involved is substantially less than the effective population size. In contrast, intense selection will lead to very rapid changes over a small number of generations. When the intensity of selection is more modest, however, the outcome is not easily seen; it seems impossible to obtain an idea of the number of generations required to achieve a given change in allele frequency, unless the actual detailed calculations are carried out.
