A cell has 36 chromosomes. After it divides by mitosis, how many chromosomes will be in each cell?
butalik [34]

Answer:

36 chromosomes in each cell

Explanation:

Mitosis is an equational division which means that it does not reduce or change the number of chromosomes in the daughter cells. Mitosis in a single parent cell produces two daughter cells each having the same DNA content and the number of chromosomes is present in the parent cell. Each chromosome after the S phase has two sister chromatids that separate from each other and are segregated to the opposite poles of the cell during anaphase of mitosis. Therefore, a cell with 36 chromosomes will form two daughter cells after one round of mitosis. Each daughter cell would have 36 chromosomes.
