You are studying a diploid organism (2N = 4) to learn more about meiosis. You are following three
markers in this cell (A, B, and D). A and B are both on chromosome 1, but D is on chromosome 2.
You have an individual heterozygous at all loci, you may choose how the alleles are configured.
e)Draw the cell again in metaphase I, but this time illustrate independent assortment relative to
your alignment in part b (again no recombination occurred; be sure to draw the metaphase plate):
f) Using the configuration found in part e, draw both cells aligning in metaphase II (be sure to draw
the metaphase plate):
g) Based on your results from part e, draw the 4 gametes produced.
h) Choose one alignment (part b or part e), and discuss how the probabilities of observing a
particular gamete can change relative to considering ALL possible alignments. Are they the same?
Different? Why/why not?
i) Draw the expected cell products from mitosis of the cell described at the beginning of this
problem and compare the outcomes of mitosis and meiosis..
