A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.
  A mutation is a permanent change in the DNA sequence of a gene.   There are two ways in which a DNA mutation can occur:   1) Mutations can be inherited.This means â¦ that if a parent has a mutation in his or her DNA, then the mutation is passed on to his or her children.   2) Mutations can be acquired.or example, this can happen during crossover during the formation of gametes. Substitution mutations happen when one nucleotide (the smallest unit of DNA) is replaced by another. These are caused by a number of chemicals that look like something in between both of those nucleotides.
