Questions

The diаgrаm belоw shоws spermаtоgenesis (on the left) and oogenesis (on the right) followed by a fertilization event.  The numbered circles are cells.  The long purple bars in the cells are X chromosomes while the short blue bars in the cells are Y chromosomes.  Bell #8 is the zygote resulting from fertilization.          a.  Where has the non-disjunction occur?  Use cell numbers to help you explain the location of the non-disjunction.       b.  What non-disjunction syndrome does this illustration demonstrate?  How do you know?

Infоrmаtiоn fоr questions 10-15 The figure below shows indifference curves for а consumer who consumes good X (on the horizontаl axis) and good Y (on the vertical axis). The utilities of the indifference curves are 100, 200, 300, 400, and 500 (it’s up to you to determine which indifference curve corresponds to which utility). Note: the answers to the questions in this group won’t be exact. To have exact answers, we’d need an exact utility function and take derivatives. Since all we have are graphs, the answers will necessarily be approximate. The point is to make the best approximations that you can, using the limited graphical information. To see the figure as clearly as you can, try to have it on a computer screen and enlarge it; also, use a ruler. Enter all answers as positive numbers. Your answer must be within the approximation specified in each question. If the answer cannot be obtained from the figure, even as an approximation, enter 0. Starting at the same point, X=4 and Y=15, how much is her marginal utility with respect to Y? Your answer must be within 5 units of the best approximation possible from the figure.
