Question

Though the stages of meiosis have the same names as the stages of mitosis, they exhibit fundamental differences. What are the main differences between the two processes?

Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is introduced in meiosis, but not in mitosis.

b

Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is reduced in meiosis, but not in mitosis.

c

Metaphase and telophase portions of meiosis and mitosis are the same. Meiosis and mitosis are also the same, except for the number of chromosomes. Anaphase I and anaphase are different.

d

Prophase and telophase portions of meiosis and mitosis are the same. Meiosis II and mitosis are also the same and have the same number of chromosomes. Anaphase I and anaphase are different.

Explanation / Answer

The answer is a

Meiosis proceeds in two stages Meiosis I and Meiosis II. In meiosis I chromosomes number is reduced to half while Meiosis II is equational division and maintaining the halved number of chromosomes. In prophase of Meiosis I non-sister chromatids cross over and exchange genetic material during anaphase hence genetic variation is introduced in Meiosis.
