The correct Answer is:
To determine when actual haploidity in terms of DNA occurs during meiosis, we need to analyze the different phases of meiosis and the changes in chromosome number and DNA content that occur during these phases. ### Step-by-Step Solution: 1. **Understanding Meiosis Phases**: - Meiosis consists of two main stages: Meiosis I and Meiosis II. Each of these stages has several phases: prophase, metaphase, anaphase, and telophase. 2. **Interphase and DNA Replication**: - Before meiosis begins, the cell undergoes interphase, which includes the S phase where DNA replication occurs. At this point, the cell has 2N chromosomes and 2C DNA content. 3. **Meiosis I**: - In Meiosis I, homologous chromosomes are separated. - At the end of Meiosis I (specifically during Telophase I), the daughter cells are formed with N chromosomes (haploid) but still contain 2C DNA because the DNA has not yet been divided. 4. **Meiosis II**: - Meiosis II resembles mitosis, where sister chromatids are separated. - During Anaphase II, the sister chromatids are pulled apart, resulting in individual chromosomes. 5. **Final Outcome**: - After Anaphase II, the cells are haploid in terms of both chromosome number (N) and DNA content (C). Each daughter cell will have half the amount of DNA compared to the original diploid cell. 6. **Conclusion**: - The actual haploidity in terms of DNA occurs after Anaphase II, where both the chromosome number and the DNA content are halved. ### Answer: The correct answer is **B) Anaphase 2**.
