C. Incomplete dominance
Step-by-step explanation:
Incomplete dominance occurs when two alleles (a form of a gene that creates traits) do not combine completely, this means one of the alleles is not dominant over the other and thus any of those traits is being expressed. In this way, instead of one trait being the dominant of two traits, the two alleles or traits blend a create a new one, called a third phenotype which is considered as intermediate heritance in which the dominance is not complete. Thus, the blending of traits or alleles is called "Incomplete dominance" as any of the traits is dominant but blend to create a new form.
