Question
Gametes or sex cells undergo which type of cell division?
a. Mitosis
b. Meiosis I only
c. Meiosis II only
d. Meiosis I and II
Solution
Gametes or sex cells undergo Meiosis I and II. So, the correct answer is d. Meiosis I and II.
Here's a step-by-step explanation:
-
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
-
Meiosis I: This is the first division and is referred to as reductional division. The number of chromosomes is reduced from 46 (diploid) to 23 (haploid). The stages of Meiosis I include Prophase I, Metaphase I, Anaphase I, and Telophase I.
-
Meiosis II: This is the second division, also known as equational division. It is similar to mitosis. The sister chromatids separate. The stages of Meiosis II include Prophase II, Metaphase II, Anaphase II, and Telophase II.
-
At the end of Meiosis II, four haploid cells are produced, which develop into gametes.
