With incomplete dominance, what phenotype is seen when there is a heterozygous genotype present?

An intermediate phenotype between the homozygous genotypes parents.

Explanation:

Dominance in genetics, refers to the phenomenon in which one variant (allele) of a gene on a chromosome masks or overrides the effect of the other variant of the same gene on the other copy of the chromosome.

Different kinds of dominance include; complete dominance, incomplete dominance, and co-dominance.

Incomplete dominance occurs when the phenotype of the heterozygous genotype appears different from the phenotypes of the homozygous genotypes and it is often intermediate.

For example, when a cross between an RR with an rr yields an Rr, we have an incomplete dominance.
