How many possible phenotypes are there for ABOblood groupsa)8b)6c)4d)3Correct answer is option 'C'. Can you explain this answer?

Question

Answer

The genetic locus, ABO locus encodes for the ABO blood group antigens. It has 3 allelic forms – A form, B form and O form. A fetus receives one of these three alleles from each of its parents. This produces four possible phenotypes (blood types) and six possible genotypes.

Answer

Phenotype - A, B, AB, O. Phenotype means hme jo result milenge nd genotype means uska genetic makeup jo hoga so here in ABO blood grouping 4 phenotype nd 6 genotype are present.

Answer

The ABO blood group system is determined by the presence or absence of certain antigens on the surface of red blood cells. There are four main blood types in the ABO system: A, B, AB, and O. The possible phenotypes (blood types) are determined by the combination of the A and B antigens on the red blood cells.

Explanation:

Blood Type A:
- Blood type A individuals have the A antigen on their red blood cells.
- They produce antibodies against the B antigen (anti-B antibodies) in their plasma.
- The possible genotypes for blood type A are AA and AO.

Blood Type B:
- Blood type B individuals have the B antigen on their red blood cells.
- They produce antibodies against the A antigen (anti-A antibodies) in their plasma.
- The possible genotypes for blood type B are BB and BO.

Blood Type AB:
- Blood type AB individuals have both A and B antigens on their red blood cells.
- They do not produce antibodies against the A or B antigens.
- The possible genotype for blood type AB is AB.

Blood Type O:
- Blood type O individuals do not have either A or B antigens on their red blood cells.
- They produce antibodies against both the A and B antigens (anti-A and anti-B antibodies) in their plasma.
- The possible genotype for blood type O is OO.

From the genotypes mentioned above, we can determine the possible phenotypes:

Phenotype A: AA, AO
Phenotype B: BB, BO
Phenotype AB: AB
Phenotype O: OO

Therefore, there are four possible phenotypes in the ABO blood group system: A, B, AB, and O.
