A forward selection system would detect any mutation that inactivates the particular gene. There must be a selection for loss-of-function of this gene. Forward mutation selections can therefore detect a wide variety of mutations including missense, nonsense, frameshift, deletion and insertion mutations. Forward mutation rates, for this reason, are much higher than reverse mutation rates described below.
