10 How do the chromosomes at the end of meiosis I compare with the chromosomes at the end of meiosis II? A Chromosomes have one chromatid at the end of both meiosis I and meiosis II. B Chromosomes have two chromatids at the end of both meiosis I and meiosis II. C Chromosomes have one chromatid at the end of meiosis I and two chromatids at the end of meiosis II. D Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II.

To solve the problem, we need to understand the stages of meiosis and how the number of chromatids changes during these stages. 1. **Meiosis I**: This is the reduction division where homologous chromosomes are separated. At the end of meiosis I, each chromosome still consists of two sister chromatids. Therefore, the chromosomes at the end of meiosis I have two chromatids. 2. **Meiosis II**: This division is similar to mitosis, where the sister chromatids are separated. At the end of meiosis II, each chromosome consists of only one chromatid because the sister chromatids have been separated. Now, let's summarize the findings: - At the end of **meiosis I**, chromosomes have **two chromatids**. - At the end of **meiosis II**, chromosomes have **one chromatid**. Based on this analysis, the correct answer is: **D**: Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II.
