Indicate whether the following outcomes of cell division are observed in mitosis only, meiosis only, or both mitosis and meiosis
serious [3.7K]

Answer:

A. Both in mitosis and meiosis (II)

B. Mitosis

C. In both

D. Meiosis

E. Mitosis

Explanation:

Prior to every case of cell division in both mitosis and meiosis, the cell always ensures to duplicates its contents including its chromosomes. In both cases of cell division, the sister chromatids separates, apart from in meiosis I where homologous chromosomes separates to opposite poles. Only one cellular division occurs in mitosis which is involved in the growth and development of the diploid individual but in meiosis, two divisions takes place in the gametes (both male and female) to ensure that the haploid number of chromosomes is transfered from both parents each to the offspring ensuring a constant diploid offspring. Thus a diploid parent cell always produces a haploid daughter cell in the gametes during meiosis. In mitosis, the daughter cells are always identical to the parents cells.
