partial dominance

Show Summary Details

Quick Reference

In genetics, the production of an intermediate phenotype in individuals that are heterozygous for the gene concerned (i.e. the heterozygote shares a phenotype that is quantitatively intermediate between those of the corresponding homozygotes). The impact of a gene at the level of the phenotype depends on its dominance relations, but also on the conditions of the rest of the genome and on the conditions of the environment. See also penetrance.
