How are the number of chromosomes maintained during asexual reproduction?
Harrizon [31]

Answer:

<em>The number of chromosomes is maintained through the process of mitosis during asexual reproduction. </em>

Mitosis can be described as a process in which a cell divides and produces two daughter cells which are exactly similar to the parent cell. The chromosome number of the daughter cells will be the same as the parent cells. No crossing over or recombination occurs during this type of cell division. Hence, mitosis is an effective way to maintain the chromosome number of organisms which reproduce asexually.
