Question

Meiosis I is reduction division. Meiosis II is equational division due to

• A. Separation of chromatids
• B. Crossing over
• C. Pairing of homologous chromosomes
• D. Disjunction of homologous chromosomes

Answer 1

The correct option is A Separation of chromatids

Meiosis is a reduction division because the end result of this special type of cell division is four haploid cells. The first meiotic division occurs which results in two cells, each with 46 chromosomes. Then, the second round of meiotic division occurs and each of these two cells divides resulting in four haploid cells.

In meiosis II, the two chromatids of each chromosome separate from each other and go to separate daughter cells. As a result, the number of chromosomes remains the same as produced by meiosis I. Therefore, meiosis II is also called as homotypic or equational division.

So, the correct answer is option A.
