Here are the two sets of data derived from crosses in Chalmydomonas involving three genes represented by the mutant alleles a,b,and c:

Determine as much as you can concerning the arrangement of these three genes relative to one another. Assuming that a and c are linked and are 38 mu apart and that 100 tetrads are produced, describe the expected results of cross 3.
