Question

The number of chromosomes becomes half in ____________________.

• A. $Anaphase-I$
• B. $Anaphase-II$
• C. $Telophase-I$
• D. $Telophase-II$

Answer 1

The correct option is A $Anaphase-I$

When the homologous chromosomes separate and moves towards the opposite pole of the cell,but the two poles still appears in the same single cell, then it is anaphase I. The sister chromosomes of each chromatids of each chromosome remain attached to one another and don't come apart. The meiosis is a reductional cell division. It is the type of cell division that reduces the number of chromosomes in the parent cell by half and produces four daughter cells. The chromosome number reduces to half during anaphase I of meiosis.

So the correct option is (A).
