100 eggs and 100 sperms can be produced from_____and_____meiotic division respectively.

Options

A. 25,25
B. 100,25
C. 100,100
D. 25,100

Answer

To solve the question "100 eggs and 100 sperms can be produced from_____and_____meiotic division respectively," we need to analyze the processes of oogenesis (egg formation) and spermatogenesis (sperm formation).

### Step-by-Step Solution:

1. **Understanding Oogenesis**:
- Oogenesis is the process of egg formation in females.
- It starts with oogonia, which develop into primary oocytes.
- Each primary oocyte undergoes meiosis to produce one functional egg and one polar body (which is non-functional).
- Therefore, from one meiotic division, only one egg is produced.

**Conclusion**: To produce 100 eggs, 100 meiotic divisions are required.

2. **Understanding Spermatogenesis**:
- Spermatogenesis is the process of sperm formation in males.
- It begins with spermatogonia, which undergo mitosis to form primary spermatocytes.
- Each primary spermatocyte undergoes meiosis I to produce two secondary spermatocytes.
- Each secondary spermatocyte then undergoes meiosis II to produce a total of four spermatids (which mature into sperm).
- Therefore, from one meiotic division, four sperm cells are produced.

**Conclusion**: To produce 100 sperm cells, 25 meiotic divisions are required (since 100 sperm ÷ 4 sperm per meiotic division = 25).

3. **Final Answer**:
- The answer to the question is that 100 eggs can be produced from **100 meiotic divisions** and 100 sperms can be produced from **25 meiotic divisions**.

### Summary:
- 100 eggs require **100 meiotic divisions**.
- 100 sperms require **25 meiotic divisions**.
