Codominance:

1. Codominance is a type of heterozygous dominance in which both alleles separately demonstrate the allele's impact on the final phenotype.
2. In the codominance, both alleles have clear effects.
3. In the codominance condition, both alleles are completely expressed.

Blood group:

1. Each biological parent gives their child one of two ABO genes.
2. The O gene is recessive, while the A and B genes are dominant.
3. When an O gene is combined with an A gene, the blood type becomes A.
4. When an O gene is combined with a B gene, the blood type becomes B.
5. When an A gene is combined with a B gene, the blood type becomes AB.
