Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A fruit fly body cell has 8 chromosomes. After MITOSIS, how many chromosomes will each of the 2 daughter cells have?
A
4
B
16
C
8
D
None of the above
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: -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-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.

Detailed explanation-5: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.
