Mutation Frequency

Mutation Frequency

Mutation Frequency is the Frequency at which a particular (Or all and any) Mutations occur over time, within a population.

                                                                   Mutation Frequency= M./n.

Where;
         M.= Number of Mutants.

         n. = Total Population in question.

For example, if in an E. coli population the number of TonB (T1 Phage resistant) Mutants is 5360, in a total population of 3.1x10¹¹. The Mutation Frequency would be;
                                                                M.F.= 5360 / 3.1x10¹¹ = 1.8x10^-8
