AP BIOLOGY

Detailed explanation-1: -Skin colour defines incomplete dominance. Most of the skin colour is the result of two blended alleles and thus produces different skin tone. Each of the alleles contributes to expressing the final phenotype.

Detailed explanation-2: -Codominance. In people, one codominant trait that you can’t really observe by looking at a person, but many people know about themselves, is blood type. People with the AB blood type have one A allele and one B allele. Because both alleles are expressed at the same time, their blood type is AB.

Detailed explanation-3: -This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time. The allele for red flowers is incompletely dominant over the allele for white flowers. Red + white = pink.
