A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.

Dominance that occurs whenever the hybrid genotype produces a new intermediate phenotype?

When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.


What is it called when the presence of two different alleles results in intermediate phenotype?

Incomplete Dominance


What is it called when the presence of two different alleles result in an intermediate phenotype?

It is called codominance or incomplete dominance.


What is the interaction of two alleles in which both alleles can be observed in a phenotype?

Incomplete dominance


How is incomplete dominance expressed in phenotype?

In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.


How are codominant alleles and incompletely dominant similar?

Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.

When both alleles can be observed in a phenotype the interaction is called?

When both alleles contribute to the phenotype of a heterozygous the alleles are said to show the dominate alleles and sometimes the recessive but mostly the dominate alleles


What is the difference between incomplete dominance and complete dominance?

Complete Dominance: Where in the dominant gene completely masks the effect of the resesive gen in heterozygous conditions. Ex. Tt or Rr. Incomplete Dominance: When 2 or more alleles influence a phenotype. Ex. Flowers. Codominance: When both alleles for a gene are expressed in heterozygous offspring. Ex. Bloodtype.

When one trait is not completely dominant over another?

This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
