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.
When both alleles are expressed in an offspring this is called?
codominance. In codominance, both alleles contribute to the phenotype and are fully expressed in the offspring. This results in a distinct phenotype that is a combination of the traits associated with each allele.
When are both alleles expressed in offspring?
Both alleles are expressed in offspring when neither allele is dominant over the other, resulting in co-dominance. This means that both alleles are simultaneously expressed in the offspring's phenotype.
How many alleles influence a phenotype in complete dominance?
8
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 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.
How are codominant alleles and incompletely dominant similar?
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
When both alleles are expressed in an offspring this is called?
codominance. In codominance, both alleles contribute to the phenotype and are fully expressed in the offspring. This results in a distinct phenotype that is a combination of the traits associated with each allele.
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.

What is called when the presence of two different alleles results in an intermidiate phenotype?
A)Polygenic Inheritance B) Multiple AllelesC)Incomplete Dominance D) Sex-Linked GenesThe answer is C = incomplete dominancePOSTED BYLexi Garcia Velasquez
What is the difference between codominance and incomplete dominance in genetics?
Codominance is when both alleles in a gene pair are fully expressed in the phenotype, resulting in a blending or combination of traits. Incomplete dominance is when neither allele is completely dominant, leading to a phenotype that is a mix of the two alleles.
