FAQs on Meiosis - 2 Video Lecture - Biology for ACT

1. What is meiosis and why is it important?

Ans. Meiosis is a type of cell division that occurs in sexually reproducing organisms. It is important because it produces gametes (sperm and eggs) with half the number of chromosomes as the parent cell, which is essential for sexual reproduction and genetic diversity.

2. How does meiosis differ from mitosis?

Ans. Meiosis and mitosis are both forms of cell division, but they have distinct differences. Meiosis involves two rounds of division, resulting in the production of four haploid cells, while mitosis only involves one round of division, resulting in the production of two diploid cells. Meiosis also involves crossing over and genetic recombination, which contributes to genetic diversity, whereas mitosis does not.

3. What are the different stages of meiosis?

Ans. Meiosis consists of two main stages: meiosis I and meiosis II. Meiosis I involves prophase I, metaphase I, anaphase I, and telophase I. Meiosis II involves prophase II, metaphase II, anaphase II, and telophase II. Each of these stages plays a specific role in the separation and distribution of chromosomes.

4. How does meiosis contribute to genetic variation?

Ans. Meiosis contributes to genetic variation through several mechanisms. During prophase I, homologous chromosomes can exchange genetic material through a process called crossing over. This leads to the formation of new combinations of alleles. Additionally, the random assortment of chromosomes during metaphase I and II further increases genetic diversity by shuffling the genetic information.

5. What are the consequences of errors in meiosis?

Ans. Errors in meiosis can lead to various genetic disorders and abnormalities. For example, if chromosomes fail to separate properly during anaphase I or II, it can result in the production of gametes with an incorrect number of chromosomes, leading to conditions like Down syndrome. Errors in crossing over can also cause gene mutations and genetic diseases.
