Relationship between variance in allele frequencies and heritability or genetic variance components of heterozygosity for different numbers of alleles. Note that the relationships are similar in shape for different numbers of alleles, but high variance in allele frequencies can only be reached when few alleles are present, leading to compressed curves for higher numbers of alleles. Although theoretically possible, many variances in allele frequencies shown here are unlikely or impossible in reasonably sized populations (e.g., <1000 individuals) because they may require some extremely low allele frequencies.
