Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Fruit fly body cells have 8 chromosomes. After mitosis you would expect the resulting fruit fly daughter cells to have ____ chromosomes.
A
16
B
8
C
46
D
4
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: -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: -So the correct answer is ‘four chromosomes’. Was this answer helpful?

Detailed explanation-4: -Answer and Explanation: The daughter cells would all have 8 chromosomes just like the original parent cell.

Detailed explanation-5: -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.
