    Gene duplication played a critical role in evolution in that it produces redundant copies of existing genes, which are then free to mutate and adopt new functions. it is a major mechanism in which new genetic materials are generated during molecular evolution. Gene duplication is important in that it can provide new genetic material for mutation, drift and selection to act upon, which results in specialized or new gene functions.
