genome duplication
Full genetic copying
Genome duplication is the process by which an organism's entire genetic material is copied, resulting in two complete sets of chromosomes.
This can occur naturally during cell division or as an evolutionary event that doubles a species' chromosome count, creating polyploidy.
Such duplication events have been significant in the evolution of plants and some animals, providing raw genetic material for the development of new functions.
Whole genome duplication played a key role in vertebrate evolution.
