Detailed explanation-1: -This intermediate phenotype is a demonstration of partial or incomplete dominance. When partial dominance occurs, a range of phenotypes is usually observed among the offspring. Although the offspring may show a variety of phenotypes, each one will lie along a continuum bracketed by the homozygous parental phenotypes.

Detailed explanation-2: -Answer and Explanation: A situation in which the heterozygote offspring of two homozygotes show a phenotype intermediate between those of the parents is called incomplete dominance. Incomplete dominance occurs when the dominant allele does not completely dominate the recessive allele.

Detailed explanation-3: -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. If a white and black dog produce a gray offspring, this is an example of incomplete dominance.

Detailed explanation-4: -Incomplete Dominance and Codominance In incomplete dominance, the F2 generation from heterozygous plants will have a ratio of 1:2:1 with the phenotypes red, white and spotted flowers. The humans with AB blood type also show codominance where the alleles for both blood types A and B are expressed.
