What significance do individuals have for gene, chromosomal, and genomic mutations.

Gene mutations are the result of changes in the nucleotide sequence in a DNA molecule within a single gene. Result – another protein is synthesized, which leads to a change in the corresponding trait of the body. This is the most important source of hereditary variability of organisms.
With chromosomal mutations, the amount of genetic material changes.
With genomic mutations, the signs of the body change.
All this is an important source of variability in evolution and selection.
