How did crossing over affect the genetic content in the gametes? Use your results to support your answer.When crossing over, there are new combinations of genes in the gametes, and they exchange chromosomes.2. What is the ploidy of the daughter cells at the end of meiosis I? What about at the end of meiosis II?The cell becomes haploid at the end of meiosis I, whereas in meiosis II each of the 4 daughters remain haploid.3. List two differences between meiosis I and meiosis II.Meiosis I start as diploid and crossing over happens. Meiosis II starts as haploid and crossing over does not occur.4. Based on your observations in the digital exercise, what can you conclude about the severity of nondisjunction that occurs in meiosis I as opposed to meiosis II?The result and implication are severe since it can cause down syndrome. 5. Why is it necessary to reduce the number of chromosomes in the formation of gametes, but not in somatic cells?Meiosis builds cells that become gametes, so this reduction in chromosomes is critical.6.
