Question

what are the number of chromatids in a cell at the end of each stage in mitosis, meiosis I , and meiosis II ?

Answer 1

Mitosis is the equational division where chromatid get separated and moves towards the opposite poles. Daughter cells has the same genetic material as parental cell.

2C will be the chromatid number at the end of mitosis.

Meiosis I is the reduction division where homologous chromosomes get separated and move towards the opposite poles .

2C will be the chromatid number at the end of meiosis I . Because homologous chromosomes get separated but not the chromatids.

Meiosis II is the equational division where sister chromatid get separated and move toward the opposite poles .

C is the chromatid number at the end of meiosis II as sister chromatid get separated during meiosis II.
