Which mechanism produces new alleles of a gene?

Explanation:
New alleles arise when the DNA sequence of a gene is altered. Mutation introduces changes such as base substitutions, insertions, deletions, duplications, or rearrangements, creating a different version of the gene at that locus. This genetic variation is what we call a new allele. Translation and transcription don't change the DNA sequence themselves; they read or copy the existing information. Fertilization combines existing alleles from two parents, increasing variation among offspring, but it does not by itself create new genetic variants. So the mechanism that generates new alleles is mutation.
