During which stage does the cytoplasm divide to form two new cells, each with one duplicated chromosome from each homologous pair?

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

Answer: (A)

Cytokinesis happens during Telophase I in meiosis I, when the cytoplasm divides to produce two haploid cells. In this stage, the homologous chromosomes have already been separated into the two different nuclei, and each resulting cell contains one chromosome from each homologous pair, with those chromosomes still consisting of two sister chromatids. The second meiosis (Prophase II, Metaphase II, Anaphase II) involves the second division of these cells, where sister chromatids separate and cytokinesis typically occurs after Telophase II to form four haploid cells. So Telophase I best fits the description of forming two new cells with one duplicated chromosome from each homologous pair.
