Derivatives

mutational

adjective mjuːˈteɪʃ(ə)n(ə)l

Relating to mutation, especially genetic change.
random mutational changes
Example sentencesExamples
- the mutational variance was greater in females than in males
- This runaway process, described as the mutational meltdown, eventually leads to extinction.
- Consider a chromosome that is divided into two regions, one of which contains multiple mutational hot spots.

mutationally

adverb mjuːˈteɪʃ(ə)n(ə)limjuˈteɪʃ(ə)nəli

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.
Example sentencesExamples
- The data were used to estimate the number of mutationally defined genes collectively deleted by the deficiencies.
- 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'.
