Meiosis is a type of cell division in which each daughter cell receives half set of chromosomes. If the parent cell is diploid (2n), progeny produced is haploid (n). Since the number of chromosomes is halved in daughter cells, meiosis is known as reductional division.

Number of bivalents are 8 in prophase I. What is the number of chromosomes during anaphase II?
1 8
2 4
3 13
4 32
Explanation:
Meiosis II maintains the haploid number of chromosomes obtained after meiosis I while changing 2n DNA content to \(\mathrm{n}\), DNA during anaphase II will remain same i.e., 8 .

During anaphase-I
1 Sister chromatids get separated
2 Homologous chromosomes get separated
3 Both are correct
4 None are correct
Explanation:
In Anaphase-I, the homologous chromosomes separate, while sister chromatids remain associated at their centromeres.

Which is the most essential step in meiosis leading to reduction
1 Crossing over between homologous chromosomes
2 Formation of chiasmata
3 Segregation of homologous chromosomes during anaphase
4 None of the above
Explanation:
During anaphase I of meiosis I, homologous chromosomes separate from each other and start moving towards the pole. Since only one chromosome out of a pair reaches the pole, the number of chromosomes becomes half in daughter cells. This is an key event leading to reduction of chromosome number.
