incomplete dominance

n. A heterozygous condition in which both alleles at a gene locus are partially expressed, often producing an intermediate phenotype. Also called partial dominance.

incomplete dominance

Failure of one or other of two ALLELES to exert a dominant effect with the result that the PHENOTYPE has a form somewhere in between those of the two phenotypes that would be produced were either gene homozygous.

incomplete dominance

a pattern of inheritance in which a cross between two phenotypically different parents produces an offspring different from either parent but containing partial features of both. The classic example is in flower colour where, for example, crossing white and red snapdragons produces a pink offspring. Compare CODOMINANCE. See also DOMINANCE (1).
