Question

During the meiotic division, the
A. Homologous chromosomes are separated
B. Linkage is disturbed
C. Homologous chromosomes do not segregate
D. All of the above

Answer 1

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

Complete Answer:
To answer this question, first, we need to know about meiotic division. The two meiotic divisions are meiosis I, meiosis II. In meiosis, the chromosome copies (during interphase) or chromosomes and homologous chromosomes switch genetic information during the period of first cell division that is known as meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.
Now, let us find the solution from the option.
Meiosis is a type of division in which the mother cell divides twice after single rotation of DNA duplication. In meiosis I, the identical chromosomes set, switch segments and then separate, i.e., each chromosome of a homologous pair goes to the opposite pole. Thus, reduces the number of chromosomes to one half. Second division or meiosis II is a normal equational division like mitosis.

Thus, the correct option is A. i.e. Homologous chromosomes are separated.

Note: Meiosis begins following single rotation of DNA replication in cells in the male or female sex organs. The method is divided into meiosis I and meiosis II, and both meiotic divisions have many stages. Meiosis I is a kind of cell division specific to germ cells, whilst meiosis II is the same to mitosis.
