Which cell division of phase of cell division maintains the chromosomes number constant from generation to generation?

Mitosis
Meiosis
Prophase I
Zygotene

The correct answer is A. Mitosis.

Mitosis is a type of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell. This type of cell division occurs in somatic cells, which are all the cells in the body except for the reproductive cells.

Meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes as the parent cell. This type of cell division occurs in the reproductive cells, which are the eggs and sperm.

Prophase I is the first stage of meiosis. During this stage, the chromosomes condense and become visible. The nuclear envelope breaks down and the spindle fibers form.

Zygotene is the second stage of prophase I. During this stage, the homologous chromosomes pair up and form tetrads.

The other options are incorrect because they do not result in the daughter cells having the same number of chromosomes as the parent cell.
