There are fewer albino squirrels in the fused population (4%) than there were for the average of the two subdivided populations (8%). You can verify that the other homozygote also decreases in frequency in the fused population. The frequencies of both homozygotes have decreased by 4% in the fused population compared to their average frequencies in the subdivided populations. In contrast, the frequency of heterozygotes in the fused population,

Table 4.7 Allele and genotype frequencies for the hypothetical example of albino squirrels in Fig. 4.11 used to demonstrate Wahlund's principle. Initially, the total population is subdivided into two demes with different allele frequencies. These two populations are then fused and undergo one generation of random mating.
