Mutation frequency and mutation rates are highly correlated to each other. 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 .
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.
Mutation–selection balance then gives = /, and so the frequency of deleterious alleles is = /. [1] This equilibrium frequency is potentially substantially larger than for the case of partial dominance, because a large number of mutant alleles are carried in heterozygotes and are shielded from selection.
In the absence of mutation or heterozygote advantage, any allele must eventually either be lost completely from the population, or fixed, i.e. permanently established at 100% frequency in the population. [2] Whether a gene will ultimately be lost or fixed is dependent on selection coefficients and chance fluctuations in allelic proportions. [3]
Conditional mutation is a mutation that has wild-type ... This was shown to be wrong as mutation frequency can vary across regions of the genome, ...
Research suggests that the frequency of mutations is generally higher in somatic cells than in cells of the germline; [12] furthermore, there are differences in the types of mutation seen in the germ and in the soma. [13] There is variation in mutation frequency between different somatic tissues within the same organism [13] and between species ...

Mutation will have a very subtle effect on allele frequencies through the introduction of new allele into a population. Mutation rates are of the order 10 −4 to 10 −8, and the change in allele frequency will be, at most, the same order. Recurrent mutation will maintain alleles in the population, even if there is strong selection against them.
