Question

question 32 of 50
how are meiosis and mitosis similar?
a. they both produce new cells.
b. they both produce diploids.
c. they happen at the same time.
d. they both produce sex cells.

Explanation:

Meiosis and mitosis are both cell - division processes. Mitosis results in two daughter cells that are genetically identical to the parent cell (used for growth, repair, etc.). Meiosis results in four daughter cells (gametes in animals) with half the chromosome number of the parent cell. But in both cases, new cells are formed.

• Option A: Mitosis produces diploid (in most somatic cells) or haploid (in some organisms) cells with the same chromosome number as the parent (in mitosis of somatic cells in diploid organisms, diploid; in haploid organisms, haploid). Meiosis produces haploid cells. So, this option is incorrect.
• Option C: Mitosis occurs in somatic cells throughout an organism's life (in multicellular organisms) for growth and repair. Meiosis occurs in germ cells to produce gametes (at a specific time in the life cycle related to sexual reproduction). So, they do not happen at the same time.
• Option D: Mitosis produces somatic cells (not sex cells). Meiosis produces sex cells (gametes). So, this option is incorrect.

Answer:

B. They both produce new cells.
