Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a fruit fly has 8 chromosomes in each of its body cells, how many chromosomes will be in each daughter cell after mitosis?
A
2
B
4
C
8
D
16
Explanation: 

Detailed explanation-1: -Each daughter cell will have 8 chromosomes. That is correct. By the end of mitosis, there are two daughter cells. Each daughter cell will have the same amount of genetic material as the parent – 8 chromosomes.

Detailed explanation-2: -This is because when a cell undergoes mitosis, the amount of chromosomes in that cell will double (in this scenario into 16 chromosomes), but will later be divided into the two daughter cells (8 chromosomes each).

Detailed explanation-3: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.

Detailed explanation-4: -The fruit fly has 8 chromosomes (2n) in each cell.

Detailed explanation-5: -So the correct answer is ‘four chromosomes’.
