What occurs during Telophase I and cytokinesis in meiosis?

During Telophase I and cytokinesis in meiosis, the cell membrane indeed divides into two haploid cells. This phase marks the conclusion of the first meiotic division, characterized by the separation of homologous chromosome pairs into distinct daughter cells.

At this point, the chromosomes, which have already undergone replication and pairing, reach opposite poles of the cell. The nuclear membrane re-forms around each set of chromosomes, and cytokinesis follows, leading to the physical separation of the cytoplasm and the formation of two daughter cells that each contain half the original chromosome number, thus making them haploid.

The other options describe events not characteristic of Telophase I or cytokinesis. For instance, spindle fibers contracting is more relevant to anaphase, where the homologous chromosomes are pulled apart. Chromosomes condensing occurs primarily during prophase, and homologous chromosomes pairing up takes place during prophase I, not Telophase I.
