Question

The second division of meiosis is
(a) Equational division
(b) Reductional division
(c) Multiplied division
(d) None of the above

Answer 1

Hint: Equational division is compared with reduction division, which results in a halving of the number of chromosomes in the cell.

Complete answer:To solve this question, first, we should learn about Meiosis. Meiosis is a complex mechanism that means no two gametes are the same. It also means that each generation produces the same amount of genetic material as that of the previous generation. If we can't generate gametes then the number of chromosomes would increase with each new generation.
Now lets us find the solution from the given options-
Meiosis II is an equational division, as it does not minimize the number of chromosomes. It is similar to mitosis where the sister chromatids are separated, producing four daughter haploid cells. So, Equational division is the correct answer.
The first meiosis division is also regarded as reductional division, since it eliminates the genetic material from diploid to haploid. So, Reductional division is an incorrect answer. Thus, option B is an incorrect option.
Cell multiplication is the mechanism by which several cells are produced from pre-existing cells. Normal cells are compounded by 'mitosis' which is a single cell split into two. So, Multiplied division is an incorrect answer. Thus, option C is an incorrect option.

Thus, option A is the correct answer i.e. Equational division

Note:Equational division is a process of animal and plant cell reproduction; a widely used synonym for mitosis. The original number of chromosomes in the cell is conserved as a consequence of equational division.
