Meiosis II performs

Options

A. separation of sex. Chromosomes
B. synthesis of DNA and centromeres
C. separation of homologous chromosomes
D. separation of chromatids

Explanation

**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 cells from one diploid cell. It consists of two main stages: Meiosis I and Meiosis II.

2. **Meiosis I**: In Meiosis I, homologous chromosomes (pairs of chromosomes, one from each parent) are separated. This is known as reductional division because it reduces the chromosome number from diploid (2n) to haploid (n).

3. **Meiosis II**: Meiosis II follows Meiosis I and is similar to mitosis. It involves the separation of sister chromatids, which are the identical copies of a chromosome that are connected at the centromere.

4. **Identifying the Function of Meiosis II**: The question specifically asks about the function of Meiosis II. During this phase, the sister chromatids are separated and pulled to opposite poles of the cell.

5. **Choosing the Correct Option**: Among the options provided:
- a) Separation of sets of chromosomes
- b) Synthesis of DNA and centromeres
- c) Separation of homologous chromosomes
- d) Separation of chromatids

The correct answer is **d) separation of chromatids**, as this accurately describes the primary function of Meiosis II.

**Final Answer**: Meiosis II performs the separation of chromatids (Option D).
