Gene duplication is a process that results in the creation of an additional copy of a gene. Over evolutionary time, these duplicated genes can accumulate mutations and diverge in function, creating new genes and increasing the size of a genome. Gene duplication is not a type of point mutation, is not limited to diploid species or organisms without functional DNA-repair enzymes, and is not similar in effects to a deletion mutation.
