Genetic mutation

Genetic mutations are sudden, heritable mutations that occur in genomic DNA molecules. At the molecular level, genetic variation refers to a change in the structure or arrangement of base pairs in a gene. According to the changes of bases, gene mutations can generally be divided into two major types: base substitution and frameshift mutation. Although genes are very stable, they can accurately replicate themselves during cell division. Hiddenness is relative. Under certain conditions, genes can also suddenly change from the original form of existence to another new form of existence, that is, at a site, a new gene suddenly appears instead of the original gene. This gene is called a mutant gene. So the performance of the offspring suddenly appeared new traits that ancestors never had. The phenomenon of gene mutation
