Where in the where in the genome do most mutations occur?

Most mutations in the genome occur in non-coding regions, particularly in introns and intergenic regions, which do not directly code for proteins. These areas are generally more tolerant to changes because they do not alter protein function. However, mutations can also occur in coding regions, where they may lead to changes in amino acid sequences and potentially impact protein function. Overall, the majority of mutations are neutral or have little effect on the organism's phenotype.
