2The changing of the structure of a gene, resulting in a variant form which may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes: mutation is, ultimately, the only way in which new variation enters the species...

The same pattern appears in tumor-associated genes undergoing either loss-of-function mutation or rearrangements.
Mere mutation of the gene structure cannot fully explain the ‘spiritual’ evolution of species.
The gene mutation appears to work by restricting calorie absorption at the cellular level.

2.1 [count noun] A distinct form resulting from genetic mutation: whether his goats were a new mutation or part of an older breed remains unclear...

Derivatives

mutational

adjective ...

This runaway process, described as the mutational meltdown, eventually leads to extinction.
Besides single step mutational events, some multiple steps mutational events were also observed.

mutationally

adverb ...

The data were used to estimate the number of mutationally defined genes collectively deleted by the deficiencies.
A data set with numerous X and autosomal genes could give repeatability of Ks, but this may represent repeatability at the chromosomal level (and be mutationally driven) rather than be on account of selection on silent sites.
By testing several cutoff values for each tree, it is possible to determine what fraction of positions is mutationally saturated, and those positions are omitted from further phylogenetic analysis.

Origin

Late Middle English: from Latin mutatio(n-), from mutare 'to change'.
