Which of the Following Occur in Telophase I of Meiosis

Question

Which of the following occur in telophase I of meiosis?  
A) Nuclear envelope formation
B) Pairing of homologues
C) Formation of a bipolar spindle
D) Crossing over
E) Condensation of chromosomes

Accepted Answer

In telophase I of meiosis, the nuclear envelope reforms around each set of chromosomes, separating them into two nuclei. Homologous chromosomes have already separated during anaphase I, so option B is incorrect. Formation of a bipolar spindle occurs during both meiosis I and meiosis II, so option C is not specific to telophase I. Crossing over occurs during prophase I, not telophase I, so option D is also incorrect. Lastly, chromosomes begin to condense during prophase I, and remain condensed throughout meiosis, so option E is incorrect for telophase I specifically.
