Question
What change occurs to the number of chromosomes in mitosis?
- Number of chromosomes is doubled
- Number of chromosomes is decreased to half.
- Number of chromosomes remain unaffected.
- No split of chromosomes.
Hint:
Mitosis results in two identical daughter cells which resembles the parent cell.
The correct answer is: Number of chromosomes remain unaffected.
- Mitosis is the cell division that occurs in somatic cells
- Following mitosis, the two daughter cells produced are identical to the parent cell
- The number of chromosomes inherited by the daughter cells remain the same
- If the parent cells have 23 pairs of chromosomes, after mitosis, each of the two daughter cells will also have 23 pairs of chromosomes
- Reduction in number of chromosomes by half occurs during meiosis, where gametes are formed
