If mother has blood group B, fathe has A group, the offspring will be of :-

Options

A. A
B. O
C. AB
D. any of the above

Answer

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

### Step 1: Identify the Genotypes of Parents
- The mother has blood group B. The possible genotypes for blood group B are IBIB (homozygous) or IBIO (heterozygous). We will consider the heterozygous condition (IBIO) for this cross.
- The father has blood group A. The possible genotypes for blood group A are IAIA (homozygous) or IAIO (heterozygous). We will also consider the heterozygous condition (IAIO) for this cross.

### Step 2: Set Up the Punnett Square
- We will set up a Punnett square to visualize the possible combinations of alleles from the parents.

| | IA | IO |
|-------|------|------|
| IB | IAIB | IBIO |
| IO | IAIO | IIOO |

### Step 3: Determine the Blood Groups from the Genotypes
- From the Punnett square, we can determine the blood groups of the offspring:
- IAIB → Blood group AB
- IBIO → Blood group B
- IAIO → Blood group A
- IIOO → Blood group O

### Step 4: List the Possible Blood Groups
- The possible blood groups for the offspring are:
- A (from IAIO)
- B (from IBIO)
- AB (from IAIB)
- O (from IIOO)

### Conclusion
- Therefore, the offspring can have any of the following blood groups: A, B, AB, or O.
