Answers (1)


The consequence of duplicate gene action is typically increased fitness due to the redundancy and specialization of the duplicated genes. Duplicated genes can evolve independently, allowing one copy to specialize in a particular function while the other copy maintains the original function. This redundancy also provides a backup copy in case one copy is lost or mutated.
