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.
an allele combination in which two characteristics blend and both alleles can express themselves; one example is red, white, and pink snapdragons.
One allele is not expressed, but the other allele expresses itself normally so that the phenotype gets half the dose of the effect.
Refers to a pair of alleles, neither of which displays dominance, the phenotype of a heterozygote being intermediate between the phenotypes of the two homozygotes.
Condition in which the heterozygous phenotype is intermediate between the two homozygous phenotypes.
The condition that results when two different alleles together produce an effect intermediate between the effects of the same two genes in a homozygous condition.
A situation in which neither gene within a gen pair is dominant to the other, with the result that both are expressed in the phenotype which is intermediate between the two traits.
A heterozygote whose phenotype is intermediate between the phenotypes of the two homozygotes. 273
A type of inheritance in which the heterozygote has a phenotype intermediate to those of the homozygous parents. PICTURE
failure of a dominant phenotype to be fully expressed in an organism carrying a dominant and a recessive allele; the result is usually an intermediate between the homozygous dominant and the recessive forms
Takes place when both members of an allele pair manifest themselves. The heterozygote can be distinguished by either of its homozygous parents.
The situation in which both alleles of a heterozygote influence the phenotype. The phenotype is usually intermediate between the two homozygous phenotypes. The situation in which a heterozygote shows a phenotype somewhere (but not exactly half-way) intermediate between the corresponding homozygote phenotypes. (Exact intermediacy is no dominance.)
The recessive allele is not masked completely by the dominant allele. Both will have an effect on the phenotype.
Two alleles provide for a blending effect to provide for a phenotype that is not exact to either
A mode of inheritance in which the heterozygote has a phenotype that is intermediate between the phenotypes of either homozygotes. For instance for snap dragon flowers, if one homozygote is red, the other white, then the heterozygote will be pink. Incomplete dominance usually arises if one gene does not express a product and its other allele expresses an insufficient amount of product to mask the first allele.
