Question

The second division in meiosis is called
A.Equational division
B.Reduction division
C.Multiplied division
D.None of these

Answer 1

Meiosis consists of two divisions that take place in rapid succession, with the chromosomes replicating only once. Thus a parent cell produces four daughter cells, each having half the number of chromosomes and half the number of nuclear DNA amounts present in the parent cell.
The two divisions of meiosis are called the first and the second meiotic divisions or meiosis-I and meiosis-II.

Complete answer:
The meiosis I is a reductional division in which homologous chromosomes separate after crossing over. Meiosis II is an equational division in which centromere splits and each chromosome separates into two chromatids, which move towards opposite poles.

So, the correct answer is option A. Equational division

Additional information:
Significance of meiosis.
Formation of gametes - meiosis produces gametes for sexual reproduction
Formation of spores - meiosis produces spores in plants for asexual reproduction
Maintenance of chromosome number - meiosis halves the chromosome number in the gametes so that fertilization may restore the original diploid number in the zygote
Introduction of variations - meiosis provides a chance for the formation of new combinations of chromosomes. This brings about variations. The new combination are produced (i) by crossing over in prophase I and by (ii) random distribution of paternal and maternal (homologous) chromosome between the daughter cells in anaphase -I. Variations help animal and plant breeders to improve the races of useful animals and plants.

Note:
Mitosis is the division of a parent cell into two identical daughter cells, each with a nucleus having the same amount of DNA, the same number and kind of chromosomes and the same hereditary instructions as the parent cell. Hence, it is also known as the equational division.
