Question

An example of codominance could be


A white flower crossed with a red flower resulting in a pink flower


A white flower crossed with a red flower resulting in a flower that has both red and white petals


A white flower crossed with a red flower resulting in a red flower


A white flower crossed with a red flower resulting in a white flower

Answer 1

"A white flower crossed with a red flower resulting in a flower that has both red and white petals" — this is codominance.

Explanation: in codominance both alleles are fully expressed simultaneously (distinct red and white patches). By contrast, a pink offspring is incomplete dominance (blending), and all-red or all-white offspring reflect complete dominance of one allele. Examples of codominance: roan cattle (red + white hairs) and the ABO blood group (A and B codominant).
