Question

Humans produce skin cells by mitosis and gametes by meiosis. The nuclei of skin cells produced by mitosis will have

Answer 1

Ans.

In humans and other higher organisms, two types of cell division, known as mitosis and meiosis takes place. Somatic cells or normal body cells of humans get divided by mitosis, while gametes are produced through meiosis.

During mitosis, a mother cell gets divided into two daughter cells and each daughter cell consists same number of chromosomes as in mother cell. In humans, 46 chromosomes are present in each cell. Thus, the skin cells, produced by mitotic division will have 46 chromosomes in their nuclei.

Answer 2

The nuclei of the skin cells produced by mitosis will have identical genetic material as that of the parent cell.

It is because mitosis is a type of cell division in which a parent cell divides into two daughter cells, each having equal and identical chromosomes as that of the parent cell.

In addition, events like crossing over do not take place due to which no genetic variation is developed in the daughter cells.

The process of mitosis is mainly involved in the repair and growth of the body.
