Codominance and Incomplete dominance

When one allele is not dominant over another, resulting in a blended phenotype for heterozygous offspring is considered....

• Incomplete Dominance

• Codominance

Some flowers are controlled by codominance. Red flowers (RR), blue flowers (BB) and Speckled flowers (RB).

• 2 red, 2 speckled

• 2 red, 2 blue

• 2 blue, 2 speckled
