Some features are polygenic, which means they are regulated by several genes. Traits in polygenic inheritance frequently form a phenotypic spectrum rather than falling into distinct groups.
An allele is a genetic variety. Some genes have many versions that are all situated at the same place, or genetic locus, on a chromosome. Humans are referred to as diploid creatures because they contain two alleles at each genetic locus, one from each parent.
Overdominance is a rare genetic situation in which the phenotype of the heterozygote is outside the phenotypic range of both homozygote parents, and heterozygous people have better fitness than homozygous individuals.
