In science:

If there is no new genetic input through mutation or migration, the genetic variability within a population decreases with time.
Biological Evolution and Statistical Physics
Variable mutation rates are used extensively in the genetic-algorithms literature.
Biological Evolution and Statistical Physics
PIKAIA incorporates only the two basic genetic operators: uniform one-point crossover, and uniform one-point mutation.
Computational Asteroseismology
Thus, by working with the genomes, Rikvold and Zia account for the genetic mutations explicitly and use the genotypes to label the different species.
Evolutionary ecology in-silico: Does mathematical modelling help in understanding the "generic" trends?
Two main points of the Eigen model are about the quasispecies which is defined as a stationary distribution of genetically close sequences, centered around one or several master sequences, and the existence of an error threshold above which all information is lost because of accumulating erroneous mutations.
Quasispecies distribution of Eigen model
This property is called identity by descent in population genetics and this mutation model known as the infinitely-many-alleles, or simply infinite-alleles, mutation model [56, 57].

A Factorial Experiment on Scalability of Search Based Software Testing
The stochastic dynamics is given by a system of interacting measure-valued diffusions and the driving mechanisms include resampling (pure genetic drift) as diffusion term, migration, selection and mutation as driftterms.
Duality for spatially interacting Fleming-Viot processes with mutation and selection
However, they are rudimentary as they only allow to study nucleotides evolution, not genetic patterns mutations.
Chaos in DNA inversions (Draft paper)
As illustrated in (7), the non-uniform mutation genetic operator employed by the real coded GA selects 1 variable, j, and sets this variable equal to a non-uniform random number (Michalewicz, 1996).

The economic counterparts of genetic heredity, mutations, and natural selection are imitation, innovation, and positive profits.
Does Meaning Evolve?
Above the error threshold, natural selection is no longer able to counteract mutation-accumulation, and the result is evolutionary dynamics governed by essentially random genetic drift.
