Mutation Rate

Measurements Of Mutation Rate, Human Mutation Rates, Factors Influencing The Mutation Rate, The Origin Of Spontaneous Mutations

Mutation rate refers to the frequency of new mutations per generation in an organism or a population. Mutation rates can be determined fairly precisely in experimental organisms with short generation times, such as bacteria or fruit flies. Human mutation rates are more difficult to determine accurately. Mutation rates can be used as a "molecular clock" to determine the time since two species diverged during their evolution.
