Final answer:
Meiosis II resembles mitosis in that sister chromatids separate during anaphase II, and the stages of meiosis II mimic those of mitosis, except that the cells are haploid. The separation of sister chromatids is the reason why option b is correct.
Step-by-step explanation:
The second meiotic division, also known as meiosis II, resembles mitosis in several ways, most notably in that sister chromatids separate during anaphase II, similar to the separation that occurs during mitotic anaphase. Additionally, meiosis II includes phases that mimic those of mitosis: prophase II, metaphase II, anaphase II, and telophase II. An important distinction to note is that meiosis II follows meiosis I, which includes pairing of homologous chromosomes and crossing over, events not seen in mitosis or meiosis II. Therefore, the correct answer to the question "The second meiotic division resembles mitosis because:" would be option b) Sister chromatids separate.
During prophase II, chromosomes condense just as they do in prophase of mitosis. The metaphase, anaphase, and telophase stages also mimic their mitotic counterparts, but it's important to remember that the cells at the start of meiosis II are haploid as a result of the previous division during meiosis I, hence the starting genetic material differs.
