Which phase of Meiosis I is most similar to mitosis?

• A. Anaphase I
• B. Metaphase I
• C. Prophase I
• D. Telophase I

Answer: (D)

Verified step by step guidance

1. Understand the basic stages of mitosis: prophase, metaphase, anaphase, and telophase, where the cell divides to produce two identical daughter cells.
2. Review the stages of Meiosis I: prophase I, metaphase I, anaphase I, and telophase I, which is the first division in meiosis leading to the production of gametes.
3. In mitosis, during telophase, the chromosomes arrive at opposite poles, the nuclear envelope re-forms, and the cell prepares to divide. This is similar to telophase I in meiosis, where homologous chromosomes reach the poles and the cell begins to divide.
4. Compare the events of telophase I in meiosis with telophase in mitosis: both involve the reformation of the nuclear envelope and the division of the cytoplasm, although meiosis I results in two non-identical cells due to crossing over and independent assortment.
5. Conclude that telophase I in meiosis is most similar to telophase in mitosis because both involve the completion of cell division processes, although the genetic outcomes differ.
