During anaphase I of meiosis

Options

A. homologous chromosomes separate
B. non-homologous autosomers separate
C. sister chromatids separate
D. non -sister chromatids separate

Explanation

**Step-by-Step Solution:**

1. **Understanding Anaphase I**: Anaphase I is the third stage of meiosis I, where the key event is the separation of homologous chromosomes.

2. **Homologous Chromosomes**: Before anaphase I begins, homologous chromosomes are paired together in a structure known as a tetrad, which consists of four chromatids.

3. **Role of Spindle Fibers**: During anaphase I, spindle fibers, which are structures that help in the movement of chromosomes, begin to pull the homologous chromosomes apart.
