chromosome doubling

Complete set replication

Chromosome doubling is the replication of a cell's entire chromosome set, resulting in twice the normal number.

This occurs naturally during cell division or can be induced artificially using chemicals like colchicine.

Plant breeders use chromosome doubling to create fertile hybrids from sterile crosses or to produce larger, more vigorous plants: Chromosome doubling turned the sterile hybrid into a fertile new species.
