<span>The answer is C. Crossing over mostly
occurs during meiosis I when sister chromosomes are lined up in the metaphase
plate awaiting anaphase I where the sister chromosomes are pulled to separate daughter
cells by spindle. It is during this period that the chromatids of the sister
chromosomes come together at a point (chiasma) and share genetic material in a process called
crossing over. </span>
