Nuclear membrane reforms, cytoplasm divides, four daughter cells formed that are genetically different occur during which phase?

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

Answer: (A)

Telophase II. In this stage of meiosis, the chromosomes arrive at the poles, the nuclear envelope reforms around each set, and cytokinesis finishes the process, producing four separate haploid daughter cells. Those cells are genetically different because crossing over occurred in earlier prophase I and the chromosomes were assorted independently during meiosis I, so the final four cells carry different allele combinations. This sequence wouldn’t fit telophase I (which ends with two cells) or the other stages, which occur before the final formation of four distinct cells.
