Make sure to answer each part of the question 

How does eukaryotic cellular division differ from prokaryotic?

1. Describe how cytokinesis differs in plant and animal cells. 
2. Down syndrome, the most common serious birth defect in the U.S., is caused by an extra copy of chromosome 21.  Explain how a gamete could end up with an extra chromosome.
3. How would you assess the likelihood of a recombination event separating two closely spaced genes on the same chromosome verses two that are distant from one another (but still on the same chromosome)?
4. An organism has 6 chromosomes (2n = 6) or 3 pair of homologous chromosomes.  Assuming no crossing over occurs, how many different combinations of maternal and paternal chromosomes would be possible in its gametes?  Remember that each gamete will contain three chromosomes, and each of these will be either maternal OR paternal.  (Denote maternal chromosomes M1, M2, M3 and paternal chromosomes P1, P2, P3.)  List the possible combinations.  (Remember the formula in 2n, so in this case 23 = 8.)
