-
Both Myers and Dunford pointed out those heterozygotes for the type of chromosomal fusion in question did not necessarily have to suffer from genetic disease or infertility.
-
For example if two alleles exist in a population, and the heterozygotes between them are intermediate between the two homozygotes on a log scale, then variation in selection coefficients will generally cause one allele to win out.

-
Once established in a deme, a negatively heterotic one with a selective disadvantage for heterozygotes–DW gene arrangement can spread in homozygous form through a subdivided population by random local extinction and colonization.
-
The human sickle cell allele has harmful effects in homozygotes and survives in a population only because it confers resistance to malaria in heterozygotes.

-
If you have two genes, each with two alleles, and it happens that genotypes AABB and aabb have high fitness, with the other double homozygotes AAbb and aaBB having lower fitness, and the various heterozygotes in between, then when you plot population mean fitness against the gene frequencies of alleles A and a you get two peaks with a valley in between.

Thus, only one of the two loci need be inactivated, and recessive lethals can be maintained as heterozygotes.

Balanced polymorphisms may occur when heterozygotes are favored or when when selection is frequency dependent.
