Assume that there are 12 map units between two loci in the mouse and that you are able to microscopically observe meiotic chromosomes in this organism. If you
examined 200 primary oocytes, in how many would you expect to see a chiasma between the two loci?

Under what circumstance might two loci be on the same chromosome but behave as if independently assorting in crosses?

Assume that a cross is made between AaBb and aabb plants and that all the offspring are either AaBb or aabb. These results are consistent with _.
