Can you give a few examples of incomplete dominance and codominance?
First let's start with a few definitions.
With incomplete dominance, a cross between organisms with two different phenotypes produces offspring with a third phenotype that is a blending of the parental traits. With codominance, a cross between organisms with two different phenotypes produces offspring with a third phenotype in which both of the parental traits appear together.
Here are a couple of examples: Incomplete dominance is seen in wavy hair. It is a new phenotype that occurs when one parent has straight hair and one parent has curly hair. An example of condominance is found in blood types. The blood type AB is made up of both A proteins and B proteins.
