Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a somatic cell has 10 chromosomes and it goes through mitosis and cytokinesis, how many chromosomes are in the daughter cells?
A
10 chromosomes
B
5 chromosomes
C
20 chromosomes
D
15 chromosomes
Explanation: 

Detailed explanation-1: -Answer and Explanation: A cell with 10 chromosomes undergoes mitosis. The number of chromosomes that each of the new cells will have is c. 10 chromosomes each.

Detailed explanation-2: -Answer and Explanation: If a cell containing 10 chromosomes divides by mitosis two daughter cells will be produced. Mitosis is the process of cell division and creates two identical daughter cells from one parent cell.

Detailed explanation-3: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

Detailed explanation-4: -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.

Detailed explanation-5: -As a result, each end pole of the dividing cell will receive 10 chromatids, with each chromatid becoming a chromosome for the cell. as a result, they will have 10 chromosomes immediately after cytokinesis, each of which is made up of a single chromatid.
