PATHOLOGY

Detailed explanation-1: -Final answer: A cell has 5 pairs of chromosomes. After mitotic division, the number of chromosomes in daughter cells will be 10.

Detailed explanation-2: -So, the correct option is ‘20’.

Detailed explanation-3: -At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes.

Detailed explanation-4: -After the parent cell divides to produce two daughter cells, there will be 32 cells after five generations of cell divisions.

Detailed explanation-5: -During anaphase chromosomes split into chromatids. Each chromatid acts as a chromosome and migrates towards the opposite pole. So, the cell initially with 5 chromosomes has 20 chromosomes during anaphase. So, the correct answer to the given question is option D, i.e., 20.
