Crossing over is unique to meiosis. Its occurrence depends on specific events early in prophase I and it has important consequences for the rest of meiosis and beyond. Which of the following is a false statement about crossing over:
a. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA.
b. Crossing over near the centromere occurs much less frequently than crossing over in other chromosomal regions because segments of DNA near the centromeres cannot break and rejoin easily.
c. As a result of crossing over, sister chromatids are no longer identical to each other.
d. Crossing over prevents homologous chromosomes from separating during meiosis I.
