Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
if the parent cell has 12 chromosomes, how many chromosomes does each daughter cell have after mitosis?
A
6
B
12
C
24
D
46
Explanation: 

Detailed explanation-1: -If the cells have 12 chromosomes during interphase, the number of chromosomes will be retained as 12 in each of the daughter cells even after the completion of mitosis.

Detailed explanation-2: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.

Detailed explanation-3: -After mitosis, two identical cells are produced with the same original number of chromosomes of the parent’s cell. In this case, if a cell has 12 chromosomes, each daughter cell will have 12 chromosomes after mitosis.

Detailed explanation-4: -Overall, meiosis results in the formation of four haploid cells from a diploid parent cell. So if a cell has 12 chromosomes at the end of meiosis I which is reduction division, it means that the parent cell would have had 24 chromosomes in prophase I.

Detailed explanation-5: -A plant cell has 12 chromosomes at the end of mitosis.
