Unformatted text preview: Say we have isolated a new paralyzed mutant that we call par . We start with a true breeding par– strain that we mate to wild type. We find that the mutation is not expressed in the F1 heterozygotes and therefore is recessive. To find out whether par– is the same as shi– we can do a complementation test since both mutations are recessive. For this test, we cross a true breeding par– strain to a true breeding shi– strain....
