Oogamous type of Fertilization involves

Options

A. a small non-motile female gamete and a large motile male gamete
B. a large non-motile female gamete and a small motile male gamete
C. a large non-motile female gamete and a small non-motile male gamete
D. a large motile female gamete and a small non-motile gamete

Explanation

**Step-by-Step Solution:**

1. **Understanding Oogamy**: Oogamous fertilization is a type of sexual reproduction. In this process, two types of gametes are involved: male and female gametes.

2. **Characteristics of Gametes**:
- The **male gamete** is typically smaller and motile, which means it can move. In humans, this is represented by sperm cells.
- The **female gamete** is larger and non-motile, meaning it does not move on its own. In humans, this is represented by the ovum (egg).

3. **Identifying the Correct Option**:
- We need to find the option that accurately describes the characteristics of the male and female gametes in oogamous fertilization.
- The correct description should state that the female gamete is large and non-motile, while the male gamete is small and motile.

4. **Evaluating the Options**:
- Option 1: A small non-motile female gamete and a large motile male gamete (Incorrect)
- Option 2: A large non-motile female gamete and a smaller motile male gamete (Correct)
- Option 3: A large non-motile female gamete and a small non-motile male gamete (Incorrect)
- Option 4: A large motile female gamete and a small non-motile male gamete (Incorrect)

5. **Conclusion**: The correct answer is Option 2: A large non-motile female gamete and a smaller motile male gamete.
