Final answer:
In meiosis, A. Prophase I and Anaphase I are unique, involving pairing and separation of homologous chromosomes. Metaphase and Telophase in meiosis II are similar to mitosis, but result in haploid instead of diploid cells.
Step-by-step explanation:
The stages that are unique to meiosis compared to mitosis include Prophase I and Anaphase I. Prophase I is unique because it involves the pairing of homologous chromosomes and crossover events, which do not occur in mitosis. Anaphase I is also unique to meiosis as it involves the separation of homologous chromosomes rather than the sister chromatids that separate during anaphase in mitosis. On the other hand, metaphase and telophase in meiosis II are remarkably similar to their counterparts in mitosis. During these phases, sister chromatids align at the metaphase plate and are subsequently separated towards opposite poles in anaphase, followed by the decondensation of chromosomes and the reformation of the nuclear membrane in telophase.
Thus, the parts of meiosis that share the most similarities with mitosis are certain stages of meiosis II, which includes Metaphase II and Telophase II. However, meiosis II results in a different number of chromosomes due to the prior chromosome number reduction in meiosis I. These stages of meiosis II mimic the events that occur during mitosis, ultimately resulting in the production of haploid cells in meiosis as opposed to diploid cells in mitosis.
