We all know that the blood is a combination of RBC, WBC, and antigens, which further determines the blood group. The most common type of blood group that most people are aware of is- A positive, B positive, AB positive, A negative, B negative, AB negative, O positive and O negative. But have you ever wondered what is the rarest blood type on earth, let's check it out.

What determines your blood group?

Your inherited genes determine your blood group. For example, if your mother has an A antigen in her blood group and father has B, the baby would have AB blood group. In a similar vein, if your father has B antigen and mother also has B antigen, there are chances that the baby would develop BB or a B blood type. On the other hand, if the mother has O blood group and father has B blood group, the baby would have B blood group because O doesn’t possess any antigen.
