If the sampling procedure resulting in a particular genotype having been caught more frequently, one's results could be erroneous. Moreover, the Wahlund Effect may be involved. Instead it would show an excess of homozygotes and a deficiency of heterozygotes. The excess of homozygotes in sub-divided populations is called the Wahlund Effect. Researchers must be careful not to allow experimental error to affect their data.
Genes segregate normally into gametes.
Gametes are equal in fertility. The adult population is very large. Adults in the population mate at random. All genotypes are equal in their viability. Adult genotypes reflect the genes they contribute to the gene pool.
