The correct Answer is:
To determine during which stage of meiosis the haploid condition is reached, we can follow these 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 cells from one diploid cell. It consists of two main stages: Meiosis I and Meiosis II. 2. **Meiosis I**: In this stage, homologous chromosomes are separated. The cell starts as diploid (2N) and after the completion of Meiosis I, it divides into two cells, each containing half the number of chromosomes. However, these chromosomes are still in the form of sister chromatids. 3. **Meiosis II**: This stage resembles mitosis. The two haploid cells produced in Meiosis I undergo a second division where the sister chromatids are separated, resulting in a total of four haploid cells. 4. **Identifying the Haploid Condition**: The key point is that the haploid condition (N) is first achieved at the end of Meiosis I. After this stage, the cells are haploid, but they still have duplicated chromosomes (sister chromatids). 5. **Conclusion**: Therefore, the haploid condition is reached at the end of Meiosis I, specifically during the telophase of Meiosis I when the two daughter cells are formed. ### Final Answer: The haploid condition is reached during **Meiosis I**. ---
