The two sets of chromosomes reach the opposite pole of the cell in:

Explanation

The two sets of chromosomes reach the opposite poles of the cell during Anaphase I of meiosis. Here are explanations for each of the options:1. Leptotene: Leptotene is the initial sub-stage of meiosis, during which chromosomes begin to condense but are not yet involved in significant movement toward the poles.2. Diplotene: In Diplotene, homologous chromosomes start to separate, but they are still connected at chiasmata. The separation is not complete at this stage.3. Metaphase I: In Metaphase I, homologous chromosomes align along the cell's equator. They are attached to the spindle fibers but have not yet separated into opposite poles.4. Anaphase I: Anaphase I is the sub-stage where homologous chromosomes are pulled apart and move to opposite poles of the cell. This is the first stage in meiosis where chromosome separation occurs.5. Diakinesis: In Diakinesis, chromosomes continue to condense, and chiasmata become more evident. However, the significant movement of chromosomes to opposite poles has not yet occurred at this stage.So, the correct answer is Anaphase I.
