Division of human egg is:

Options

A. Holoblastic, equal
B. Meroblawstic
C. Holoblastic, unequal
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Egg Division Types**: The division of human eggs can be categorized into two main types: Holoblastic and Meroblastic. It's essential to understand these terms to identify the correct type of division.

2. **Holoblastic Division**: In Holoblastic division, the entire egg divides completely. This type can be further classified into two subtypes: Holoblastic Equal and Holoblastic Unequal.

- **Holoblastic Equal**: This type of division results in equal-sized daughter cells. It is typically seen in organisms like amphibians (e.g., frogs).
- **Holoblastic Unequal**: In this type, the egg divides into cells of different sizes, which is the case in humans.

3. **Meroblastic Division**: In Meroblastic division, only a part of the egg divides, while the other part remains intact. This type is commonly observed in certain groups like mollusks.

4. **Identifying the Type of Division in Humans**: In humans, the division of the egg is characterized by Holoblastic Unequal division, where the egg divides into cells of different sizes. This is crucial for the development of the embryo.

5. **Conclusion**: Based on the information provided, the correct answer to the question "Division of human egg is:" is Holoblastic Unequal.

**Final Answer**: Holoblastic Unequal division.
