MITOSIS AND MEIOSIS

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

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

Detailed explanation-5: -Eight chromosomes are found in the somatic cells in fruit flies, suggesting they have 2 pairs of four chromosomes. Mitosis ensures that each cell generated executes the correct functions since they are similar to the original cell. The mechanism by which sex cells are formed is meiosis.
