8. How does metaphase in meiosis I and meiosis II differ?
9. A large family has a history of multiple aneuploid diseases such as Down Syndrome, trisomy-18 and Klinefelter Syndrome (XXY). The propensity to defects seems to be inherited, but the gene responsible is unknown. What types of candidate genes would be most likely to lead to aneuploidy if they were mutated?

10. Most organisms on earth spend large amounts of energy reproducing sexually, instead of using a more efficient method of asexual reproduction. Finding and competing for mates, meiosis and gamete production, and the complexities of fertilization could all be avoided if asexual reproduction was sufficient. Why isn’t it?
