Mechanisms of suppression


A suppressor is a second mutation that restores a function lost by the primary mutation. A suppressor mutation that occurs within the same gene is called an "intragenic suppressor", and a suppressor mutation that occurs in a different gene is called an "intergenic suppressor". Suppressors can arise in many ways, as indicated in the following figure.
