However, the offspring of that population reflect only a small subset of those possible gametes--and that sample may not be an accurate subset of the population at large. If alleles in the gamete pool exactly mirror those in the parent generation, and if they meet up randomly (in an infinitely large number of events), there is no reasonin fact, no wayfor allele and genotype frequencies to change from one generation to the next. 4.
