3.32 Types of mutation

Understand that many mutations are harmful but some are neutral and few are beneficial.

Gene=====mutation=======>new alleles

New alleles can be: beneficial, neutral or harmful.
Example of a beneficial mutation might be to improve an efficiency of an enzyme. Example of a harmful mutation might be a production of an enzyme that does not work. If the mutation has no particular effect, we call it a neutral mutation. Although the neutrality may change due to environmental change which can lead to harmful or beneficial mutations.
