The human germline mutation rate is approximately 0.5×10 −9 per basepair per year. [1] In genetics, the mutation rate is the frequency of new mutations in a single gene, nucleotide sequence, or organism over time. [2] Mutation rates are not constant and are not limited to a single type of mutation; there are many different types of mutations.

The rate of de novo mutations, whether germline or somatic, vary among organisms. [103] Individuals within the same species can even express varying rates of mutation. [104] Overall, rates of de novo mutations are low compared to those of inherited mutations, which categorizes them as rare forms of genetic variation. [105]

Where k is the length of a DNA sequence and is the probability a mutation will occur at a site. [5] Watterson developed an estimator for mutation rate that incorporates the number of segregating sites (Watterson's estimator). [6] One way to think of the ISM is in how it applies to genome evolution.
Mutation frequencies test are cost effective in laboratories [1] however; these two concepts provide vital information in reference to accounting for the emergence of mutations on any given germ line. [2] [3] There are several test utilized in measuring the chances of mutation frequency and rates occurring in a particular gene pool.
It is a measure of the "population mutation rate" (the product of the effective population size and the neutral mutation rate) from the observed nucleotide diversity of a population. θ = 4 N e μ {\displaystyle \theta =4N_{e}\mu } , [ 3 ] where N e {\displaystyle N_{e}} is the effective population size and μ {\displaystyle \mu } is the per ...
