In meiosis I, what is the primary event that occurs during telophase I?

• A. Chromosomes condense and the nuclear envelope breaks down while the spindle begins to form.
• B. Homologous chromosomes arrive at opposite poles, nuclei may reform, and cytokinesis produces two haploid cells whose chromosomes are still composed of sister chromatids.
• C. Homologous chromosomes pair (synapsis) and crossing over occurs between non-sister chromatids.
• D. Sister chromatids separate and move to opposite poles, producing four haploid cells.

Answer: (B)
