mutationand

Mutationand is a neologism used in discussions of evolutionary genetics to describe the interplay between mutational processes and other genetic forces such as recombination, selection, and genetic drift. The term blends “mutation” with the connective “and” to emphasize that mutations act in concert with other mechanisms rather than in isolation. Because it is not an established technical term, its precise definition varies among authors; in some usages it refers to a conceptual framework, in others to a modeling approach in simulations that apply mutation and additional processes within a single step.

Typical applications include population-genetic modeling, evolutionary algorithms, and educational explanations of how mutation interacts with recombination to shape genetic variation and fitness landscapes. In a modeling context, mutationand may describe how changing mutation rates or mutation spectra alter outcomes when coupled with selection or drift, or how epistatic interactions influence the cumulative effect of mutations.

Relationship to related concepts: mutation, recombination, mutation-selection balance, and mutational landscapes are related terms. Unlike these well-established concepts, “mutationand” is often defined situationally, which can limit comparability across studies. As a result, discussions of mutationand tend to include explicit definitions within each work to avoid ambiguity.
