Mutation Frequency Very rare naturally (due to DNS repair mechanism). 
Estimates vary from 1 in 10,000 to 1 in 1,000,000 or 1 in a million animals or once in a million lifetimes


It is true that mutations are not frequent. A mutation which gets through the various filtering processing can linger as a recessive trait for a long time within a population.

Mutations are preserved within a species as a whole. They are not present in every individual. The sum of all the traits carried around by the many members of a species adds up to a lot of variety.
