In Anaphase-I each chromosme composed of :-

Options

A. One chromatid
B. Two chromatid
C. Four chromatid
D. Many chromatid

Answer

**Solution:**

In Anaphase I of meiosis, the key event is the separation of homologous chromosomes. Each homologous chromosome is composed of two sister chromatids. Here’s a step-by-step breakdown of the reasoning:

1. **Understanding Meiosis**: Meiosis consists of two rounds of cell division: Meiosis I and Meiosis II. Anaphase I is part of Meiosis I, where homologous chromosomes are separated.

2. **Chromosome Structure**: Before Anaphase I begins, each chromosome is duplicated during the S phase of interphase. This means that each chromosome consists of two identical sister chromatids.

3. **Event in Anaphase I**: During Anaphase I, the homologous chromosomes (each still consisting of two sister chromatids) are pulled apart towards opposite poles of the cell.

4. **Composition of Chromosomes**: At the start of Anaphase I, each chromosome is still composed of two sister chromatids. Therefore, the correct answer to the question is that in Anaphase I, each chromosome is composed of **2 chromatids**.

5. **Conclusion**: Thus, the answer to the question "In Anaphase-I each chromosome composed of:" is **2 chromatids**.

**Final Answer**: 2 chromatids.
