Question

The number of phenotypes in ABO blood groups is
A.6
B.8
C.1
D.4

Answer 1

Hint:- ABO and Rhesus (Rh) blood groups are the most clinically significant in bonding rehearse and have been broadly explored in populace hereditary qualities, anthropological examinations, and disease susceptibility studies. The relationship between the ABO blood gathering and different viral contaminants have been illustrated, including dengue and hepatitis C

Complete Answer:-
- ABO blood bunch framework, the grouping of human blood dependent on the acquired properties of red platelets (erythrocytes) as controlled by the presence or non-appearance of the antigens A and B, which are carried on the outside of the red cells.
- People may accordingly have type A, type B, type O, or type AB blood. The A, B, and O blood bunches were first distinguished by Austrian immunologist Karl Landsteiner in 1901.
- Blood contains red cells with type An antigen on their surface and in its serum (liquid) antibodies against type B red cells.
- In the event that, in bonding, type B blood is infused into people with type A blood, the red cells in the infused blood will be crushed by the antibodies in the beneficiary's blood.
- Similarly, type A red cells will be annihilated by hostile antibodies in type B blood. Type O blood can be infused into people with type A, B, or O blood except if there is contradiction concerning some other blood bunch framework additionally present.
- People with type AB blood can get type A, B, or O blood.
- The ABO antigens are grown well before birth and stay all through life. Youngsters secure ABO antibodies inactively from their mom before birth, yet by a quarter of a year old enough babies are making their own; it is accepted that the improvement for such neutralizer arrangement is from contact with ABO-like antigenic substances in nature.

So, the correct answer is “option- D”

Note:- All people and numerous different primates can be composed for the ABO blood group. There are four chief sorts: A, B, AB, and O. There are two antigens and two antibodies that are generally answerable for the ABO types. The particular blend of these four segments decides a person's sort as a rule.
