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. WebApr 30, 2024 · A mutation is defined as any change in the Deoxyribonucleic Acid (DNA) sequence of an organism. These changes may happen spontaneously if there is a mistake when copying the DNA, or if the DNA sequence comes into contact with some sort of mutagen. Mutagens can be anything from x-ray radiation to chemicals.
