Glutilana Shead Simple dominance 2 alleles (ex: B and b) with 2 outcomes (ex: black and white) Incomplete dominance 2 alleles (ex R and W) with a 3/ outcome as a blend (ex: red and white and pink) Codominance Similar to incomplete but 39 outcome has parts of the other two(ex: red and white and checkered) Human blood type involves codominance - some people are type A. some people are type B, and some people are type AB. Type AB is NOT a blend of A and B. 1. Snapdragons are flowers that are incompletely dominant for color; they have phenotypes red, pink, or white. The red flowers and the white flowers are homozygous. The pink flowers are heterozygous. Red snapdragon genotype: Pink snapdragon genotype: White snapdragon genotype: Show the expected outcome of a cross of a pink snapdragon and a white one.
