There are four types of blood groups; A, B, AB, and O. If you belong to the blood group A, you have A antigens on the surface of your red blood cells and Anti-B antibodies in your blood. If you belong to the blood group B, you have B antigens on the surface of your red blood cells and Anti-A antibodies in your blood. If you belong to the blood group O, you have neither A nor B antigens on the surface of your red blood cells but you have both Anti-A and Anti-B antibodies in your blood.
| Blood Group | Antigen on red Blood cells | Antibodies in Plasma | Can Receive Blood From | Can give blood to |
| A | A | Anti-B | A&O | A&AB |
| B | B | Anti-A | B&O | |
| AB | A & B | None | All | |
| O | NONE | Anti-A & Anti-B | O | All |
Delegate your assignment to our experts and they will do the rest.
Blood group O is considered to be universal donor because it doesn’t have antigen A&B on the red blood cells. Blood group AB is considered to be universal recipient because it lacks Anti-A and Anti-B antibodies that would otherwise initiate agglutination reaction.
IA is dominant because it manifest its characteristics in both heterozygous and homozygous state. For example a father who has blood type A and B, the genotype IA IB so he will produce sperms with either an IA or an IB allele. And he can give either an IA or an IB allele to a child of his. If the mother has blood type O, her genotype must be II and she can only give an I allele to her child.
It is not possible for Michael and Danielle to have a child of blood group O as because they can only give rise to AB, AO, BB, and BO genotypes and AB, A, and B blood groups.

No switch was made at the hospital, Michael Junior and Michel inherited different genotype from their parents which ultimately resulted to a variation in their appearance due to the different phenotype.
