Which of the Following Occurs in Meiosis 1 but Not

Question

Which of the following occurs in Meiosis 1 but not in Mitosis?
A) Homologous chromosomes pair during prophase
B) Homologous chromosomes line up along the metaphase plate
C) Homologous chromosomes separate from each other during anaphase
D) All of these
E) None of these

Accepted Answer

In Meiosis 1, homologous chromosomes pair up during prophase I in a process called synapsis, which does not occur in Mitosis. Homologous chromosomes also line up along the metaphase plate in Meiosis 1, but not in Mitosis. In Meiosis 1, homologous chromosomes separate from each other during anaphase I, while in Mitosis, sister chromatids separate during anaphase. Therefore, all of these events occur in Meiosis 1 but not in Mitosis.
