Answers

The F1-hybrid plants have a different phenotype (pink flowers) than either of the true-breeding parents. This is an example of incomplete dominance.

What is incomplete dominance?

Incomplete dominance is a type of gene interaction in which both alleles of the same gene at the same locus are partially expressed, resulting in an intermediate or different phenotype. It is also referred to as partial dominance.

When none of the genes' factors are dominant, the phenotype of a heterozygous dominant individual is a mix of dominant and recessive traits. This is known as partial dominance. Consider the flower color of Mirabilis jalapa.

Height and hair color are two common examples of incomplete dominance. Offspring are unlikely to be the same height or hair color as one of their parents, but rather a blend of the two parents' phenotypes.
