Which of the following events occur during telophase I of meiosis?

• A. Homologous chromosomes separate and move to opposite poles
• B. Nuclear membranes reform around each set of chromosomes
• C. Chromosomes line up at the metaphase plate
• D. Sister chromatids separate

Answer: (B)

Verified step by step guidance

1. Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of four haploid cells. It consists of two stages: meiosis I and meiosis II.
2. Recognize that telophase I is a phase in meiosis I. During this phase, the cell completes the first division of meiosis.
3. Recall that during telophase I, the homologous chromosomes, which were separated during anaphase I, are now at opposite poles of the cell.
4. Identify that one of the key events in telophase I is the reformation of nuclear membranes around each set of chromosomes at the poles, which is crucial for the transition to the next stage.
5. Note that the other options provided, such as the separation of sister chromatids and chromosomes lining up at the metaphase plate, occur in different stages of meiosis (sister chromatids separate during anaphase II, and chromosomes line up at the metaphase plate during metaphase I and II).
