There are two special types of inheritance: Incomplete Dominance and Codominance
Incomplete Dominance – A heterozygous situation where the two different alleles blend together.

One parent flower is red (CR CR). The other parent is white (Cw Cw).

The second type of special inheritance is called codominance.
Codominance – A heterozygous situation where the two different alleles are equally dominant and they both get expressed.

To review: Codominance happens when both alleles are
equally dominant and both alleles get expressed.

Incomplete dominance happens when the heterozygous alleles get blended.
