Answer 1

Answer:

Answer:

Answer:a.) DNA copying is accompanied by the creation of an additional cellular material, after which the DNA copies separate, each with its own cellular apparatus. Effectively, a cell divides to give rise to two cells. Thus, chromosome number remains unchanged. For example: Replica of Amoeba by binary fission.

Answer:a.) DNA copying is accompanied by the creation of an additional cellular material, after which the DNA copies separate, each with its own cellular apparatus. Effectively, a cell divides to give rise to two cells. Thus, chromosome number remains unchanged. For example: Replica of Amoeba by binary fission.b.) In case of asexual reproduction the whole set of chromosomes is replicated and transferred to the next generation. For example, reproduction of Amoeba by binary fission. In case of sexual reproduction the chromosome number is halved to form gametes.
