CHROMOSOMES AND CELL DIVISIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When body cells divide, each new cell should have the same number of chromosomes as the parent cell.
A
Yes
B
No
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -In mitosis, the important thing to remember is that the daughter cells each have the same chromosomes and DNA as the parent cell. The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes.

Detailed explanation-2: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Detailed explanation-3: -At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.
