WebMay 8, 2024 · Genetic mutations are slight alterations of DNA or RNA nucleotides, genes or chromosomes that may occur during replication or cell division. Random, uncorrected errors may be beneficial or harmful in relationship to evolution. Some effects of gene mutation go unnoticed. What Is Gene Mutation in Biology? WebAbstract. Deleterious mutations decrease reproductive fitness and are ubiquitous in genomes. Given that many organisms face ongoing threats of extinction, there is interest in elucidating the impact of deleterious variation on extinction risk and optimizing management strategies accounting for such mutations.
