What are clones? - ️️Genetically identical copies. The term can apply to cells or whole organisms. How are clones produced? - ️️By asexual reproduction in which the nucleus is divided by mitosis. Mitosis creates two identical copies of DNA, which are then separated into two genetically identical nuclei before the cell divides to form two genetically identical cells. These cells may not be physiclly or chemically identical as, after division, they may differentiateto form two d...
