3.32 Types of mutation

Key Points:
1. We begin with the first copy of the gene, and the process of mutation produces new alleles which in turn make new genes. The alleles are responsible for the phenotype and they can be either, beneficial, harmful or neutral.
2. An example of a beneficial mutation might be a boosted efficiency of an enzyme. Or harmfully a enzyme could be rendered useless. A neutral mutation might be an enzyme with no use at the present time, but in time, when the environment changes there could be some beneficial or harmful purpose of this.
