Blood group of the father is A and blood group of mother is B. then predict the blood group of the progeny-

Options

A. A,AB
B. A,B,AB,O
C. B,AB
D. O,A,B

Answer

To determine the possible blood groups of the progeny from a father with blood group A and a mother with blood group B, we can follow these steps:

### Step 1: Understand Blood Group Genetics
Blood groups are determined by the presence of antigens on the surface of red blood cells. The main blood group antigens are A and B, and they can combine in different ways. The possible genotypes for blood groups are:
- Blood group A can be genotype AA or AO.
- Blood group B can be genotype BB or BO.
- Blood group AB has the genotype AB.
- Blood group O has the genotype OO.

### Step 2: Determine Possible Genotypes of Parents
- The father has blood group A, so his genotype can be either AA or AO.
- The mother has blood group B, so her genotype can be either BB or BO.

### Step 3: Create a Punnett Square
We will consider the combinations of the possible genotypes of the parents.

1. **Father (AA) and Mother (BB)**:
- Possible offspring: All AB (100% AB)

2. **Father (AA) and Mother (BO)**:
- Possible offspring: 50% AB and 50% AO (which is blood group A)

3. **Father (AO) and Mother (BB)**:
- Possible offspring: 50% AB and 50% BO (which is blood group B)

4. **Father (AO) and Mother (BO)**:
- Possible offspring: 25% AB, 25% AO (A), 25% BO (B), and 25% OO (O)

### Step 4: List Possible Blood Groups
From the combinations above, the possible blood groups of the progeny can be:
- A (from AO)
- B (from BO)
- AB (from AB)
- O (from OO)

### Conclusion
Thus, the progeny can have blood groups A, B, AB, or O.

### Final Answer
The possible blood groups of the progeny are A, B, AB, and O.
