D
Telophase II
Verified step by step guidance1
Understand the process of meiosis, which consists of two consecutive divisions: Meiosis I and Meiosis II. Each division has several stages: Prophase, Metaphase, Anaphase, and Telophase.
Recall that during Meiosis I, homologous chromosomes are separated, resulting in two cells, each with a haploid set of chromosomes, but each chromosome still consists of two sister chromatids.
In Meiosis II, the sister chromatids are separated. This is similar to mitosis, where each chromosome is split into two individual chromatids.
Focus on Telophase II, the final stage of Meiosis II. At this point, the sister chromatids have been separated during Anaphase II, and each chromosome is now composed of a single chromatid.
Recognize that Telophase II results in four haploid cells, each with chromosomes composed of single chromatids, completing the process of meiosis.
