Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When one allele is not completely expressed over the other, resulting in a third phenotype that is a combination.
A
Codominance
B
Incomplete Dominance
C
Complete Dominance
Explanation: 

Detailed explanation-1: -“Incomplete dominance is a form of intermediate inheritance in which one allele for a particular trait is not expressed completely over its paired allele.”

Detailed explanation-2: -The intermediate trait appearance in between the phenotypes of homozygous traits in the heterozygote is called incomplete dominance. The formation of a third phenotype specifically with traits that results from the combination of parent alleles is known as incomplete dominance or.

Detailed explanation-3: -Cases in which one allele is not completely dominant over another are called incomplete dominance. In incomplete dominance, the heterozygous phenotype lies somewhere between the two homozygous phenotypes.

Detailed explanation-4: -Incomplete dominance occurs when neither trait is truly dominant over the other. This means that both traits can be expressed in the same regions, resulting a blending of two phenotypes.

Detailed explanation-5: -Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism’s resulting physical appearance shows a blending of both alleles. It is also called semi-dominance or partial dominance.
