If a cell at metaphase of mitosis contains 20 sister chromatids, how many chromosomes will be present in a g1 cell

The correct answer is 10 chromosome. Mitosis is the type of cell division that takes place in the somatic cells or the body cells where the parent cells divides into two daughter cells with the same genetic composition as the parent. Therefore, the number of chromosomes in the daughter cells remains the same as that of the mother cells. The opposite is the meiosis, which involves division of a germ line cells into four daughter cells which contains half the number of chromosomes as the parent.
