INCOMPLETE DOMINANCE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The phenotype of a heterozygote is a mix between both traits is explaining which type of dominance?
A
Codominance
B
Incomplete Dominance
C
Complete Dominance
Explanation: 

Detailed explanation-1: -However, sometimes the heterozygote displays a phenotype that is an intermediate between the phenotypes of both homozygote parents (one of which is homozygous dominant, and the other of which is homozygous recessive). This intermediate phenotype is a demonstration of partial or incomplete dominance.

Detailed explanation-2: -Incomplete dominance occurs in the heterozygote, in which the dominant allele does not dominate the recessive allele entirely; rather, an intermediate trait appears in the offspring. Codominance occurs when the alleles do not show any dominant and recessive allele relationship.

Detailed explanation-3: -What is Incomplete Dominance? Incomplete dominance is a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype. It is also known as partial dominance.

Detailed explanation-4: -In a heterozygous genotype, the dominant allele overrules the recessive one. Therefore, the dominant trait will be expressed. The recessive trait won’t show, but you’re still a carrier. This means you can pass it on to your children.

Detailed explanation-5: -Incomplete dominance results from a cross in which each parental contribution is genetically unique and gives rise to progeny whose phenotype is intermediate. Incomplete dominance is also referred to as semi-dominance and partial dominance. Mendel described dominance but not incomplete dominance.
