Talk about asexual cell division.

Asexual reproduction involves only mitotic cell division, therefore each offspring has exactly the same hereditary information as its parent: each daughter cell receives an exact copy of the chromosomes of the mother cell (clones). Thus asexual reproduction results in stable characteristics within a species from generation to the next: the same chromosome number is retained from generation to generation. Asexual reproduction is efficient in that it is generally rapid and often results in the production of large numbers of identical offsprings.
