Occurs when two different alleles of the same gene are both partially expressed in a heterozygote. The resulting phenotype is intermediate between the homozygous phenotypes of the two alleles. Color in a four oâ€(tm)clock flower is an example of incomplete dominance.
alleles that, when heterozygous, are two "weak" to provide the full phenotype. Two functional copies of the allele are necessary to produce sufficient gene product to give full phenotype. Also called partial dominance or absence of dominance.
In genetics, the phenomenon in which the effects of both alleles at a particular locus are apparent in the phenotype of the heterozygote.
