The fusiion of male and female gametes in course of fertilization is called

Options

A. Syngamy
B. Hologamy
C. Isogamy
D. Anisogamy

Answer

**Step-by-Step Text Solution:**

1. **Understanding Fertilization**: Fertilization is defined as the process where the fusion of male and female gametes occurs. This is a crucial step in sexual reproduction.

2. **Identifying Gametes**: The gametes involved in fertilization are haploid, meaning they contain half the number of chromosomes. The male gamete is typically referred to as sperm, while the female gamete is known as the ovum.

3. **Formation of Zygote**: When the male and female gametes fuse, they form a zygote. This zygote is diploid, as it contains a complete set of chromosomes (one set from each parent).

4. **Types of Gamete Fusion**:
- **Anisogamy**: This refers to the fusion of two different types of gametes (male and female) that differ in size and morphology.
- **Isogamy**: This is the fusion of gametes that are similar in size and shape, making it difficult to distinguish between male and female gametes.
- **Hologamy**: This involves gametes that resemble somatic cells, rather than being specialized reproductive cells.
- **Syngamy**: This is the specific term used to describe the fusion of male and female gametes during fertilization.

5. **Conclusion**: The correct term for the fusion of male and female gametes during fertilization is **syngamy**.
