In meiosis, the daughter cells differ from parent cell as well as amongst themselves due to

Options

A. segregation, independent assortment and crossing over
B. segregation and crossing over
C. independent assortment and crossing over
D. segregation and independend assortment

Explanation

To answer the question regarding how daughter cells in meiosis differ from the parent cell as well as amongst themselves, we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Understanding Meiosis**:
- Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid daughter cells from one diploid parent cell.

2. **Difference Between Daughter Cells and Parent Cell**:
- The primary difference between the daughter cells and the parent cell is that the daughter cells are haploid (n), while the parent cell is diploid (2n).
- This reduction in chromosome number occurs due to the process of **segregation**, where homologous chromosomes are separated during meiosis I, and sister chromatids are separated during meiosis II.

3. **Difference Among Daughter Cells**:
- The daughter cells differ from each other due to genetic recombination, which occurs through **crossing over**. This process happens during the pachytene stage of prophase I, where homologous chromosomes exchange genetic material.
- As a result of crossing over, the genetic makeup of the daughter cells is not identical, leading to genetic variation.

4. **Conclusion**:
- The differences observed in the daughter cells compared to the parent cell are mainly due to **segregation**, and the differences among the daughter cells themselves are due to **crossing over**.
- Therefore, the correct answer to the question is **B: segregation and crossing over**.

### Final Answer:
The daughter cells differ from the parent cell as well as amongst themselves due to **segregation and crossing over**.
