Which type of cell division is required for growth and repair of the body and which type is involved in formation of gametes?

Cells divide in two ways, depending on the type of cell: mitosis and meiosis. Each of these cell division strategies has its own set of properties. One of the most significant differences in mitosis is that a single cell divides into two identical replicas with the same number of chromosomes. Cell division like this is beneficial for fundamental growth, repair, and maintenance. A cell divides into four cells with half the number of chromosomes during meiosis. It is crucial for sexual reproduction and genetic diversity to reduce the number of chromosomes by half. Gametes formation in our body occurs by the type of cell division called Meiosis while Mitosis is the type of cell division that is involved in the growth and repair of the body.

The most crucial thing to know about mitosis is that the daughter cells have identical chromosomes and DNA as the parent cell. Diploid cells are the daughter cells that result after mitosis. Diploid cells have two sets of full chromosomes. Mitosis does not create genetic variation in normal healthy cells since the daughter cells have exact copies of their parent cell’s DNA.

Meiosis is a type of cell division in which the parent cell divides into four daughter cells, each with half the number of chromosomes. All sexually reproducing organisms contain genetic variety because of meiosis. A little piece of each chromosome breaks off and reattaches to another chromosome during meiosis. “Crossing over” or “genetic recombination” is the term for this procedure.
