50 secondary oocytes in female and 50 secondary spermatocytes in male give rise to

Options

A. 50 ova and 100 sperms
B. 100 ova and 200 sperms
C. 200 ova and 50 sperms
D. 100 ova and 100 sperms.

Answer

To solve the question regarding the number of gametes produced from 50 secondary oocytes in females and 50 secondary spermatocytes in males, we can break it down into steps:

### Step-by-Step Solution:

1. **Understanding Secondary Oocytes**:
- In females, secondary oocytes are produced during oogenesis. Each secondary oocyte undergoes meiosis to produce one ovum and one polar body.
- Therefore, from 50 secondary oocytes, we will get 50 ova (since each secondary oocyte produces one ovum).

2. **Understanding Secondary Spermatocytes**:
- In males, secondary spermatocytes are produced during spermatogenesis. Each secondary spermatocyte undergoes meiosis to produce two sperms.
- Therefore, from 50 secondary spermatocytes, we will get 100 sperms (since each secondary spermatocyte produces two sperms).

3. **Combining the Results**:
- From the above calculations, we have:
- 50 ova from 50 secondary oocytes.
- 100 sperms from 50 secondary spermatocytes.

4. **Final Answer**:
- The final result is that 50 secondary oocytes give rise to 50 ova, and 50 secondary spermatocytes give rise to 100 sperms.

### Conclusion:
The answer to the question is:
- 50 ova and 100 sperms.
