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: -After mitosis, each of the eight chromosomes are in each daughter cell. These two cells are exact copies of the original cell. We now have enough information to answer our question. In a somatic cell of a fruit fly with eight chromosomes, the number of chromosomes in each daughter cell after mitosis is eight.

Detailed explanation-3: -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-4: -Final answer: The fruit fly has 8 chromosomes (2n) in each cell. During interphase of mitosis, if the number of chromosomes at G1 phase is 8, what would be the number of chromosomes after S phase is also 8.
