Unformatted text preview: in the same gene. Say you isolate a new recessive histidine requiring mutation that we will call HisX – . In principle, this mutation could be in His3 or it could be in any of the other genes in the histidine biosynthetic pathway. In order to distinguish these possibilities we need a test to determine whether HisX the same as His3. To carry out a complementation test, one simply constructs a diploid carrying both the His3 – and HisX – alleles. An easy way to do this would be to mate a MATα HisX – strain to a MAT aaaaa His3 – strain....
