Meiosis problem help

  1. Oct 5, 2005 #1
    Hi, I'm doing some studying before the exam and I'm not clear about a certain concept regarding the following question:

    "Select the choice that is NOT true. Crossing over
    A. Occurs between non-homologous chromosomes during prophase I of meiosis.
    B. Occurs during prophase I of meiosis.
    C. Involves only two chromatids in the bivalent(tetrad)
    D. Is equal and reciprocal.
    E. Cannot take place during mitosis.

    Is the answer A? (because crossing over occurse between HOMOLOGOUS chromosomes during prophase I of meiosis?)
