What is the process called that guarantees that the number of chromosomes in gametes is half the number of chromosomes in body cells is?

Answer 1

Since gametes divide by a special process, meiosis, they will always have half the number of chromosomes as regular body cells. This is because the chromosomes only copy themselves once, however they are split apart twice. Think of it as a math problem.

If the original cell count is, for example, 2 chromosomes, and each chromosome makes a copy of itself, the cell will have 4 chromosomes. During meiosis 1, the cell divides, and the chromosomes split, resulting in each daughter cell having 2 chromosomes, the same as the original. However, in meiosis 2, they divide again without making another copy of themselves, so that by the time meiosis is done, each one of the 4 cells that results have 1 chromosome, half the number of the original cell.

2x2=4

4/2=2

2/2=1

Answer 2

Meiosis. Meiosis is the process in which gametes are produced. In meiosis, 4 haploid (think haploid- half) daughter cells are produced from the parent cell. These cells have half the number of chromosomes as the parent cell. For example, normal human cells have 46 chromosomes, where gametes have only 23.

Answer 3

Yes, gametes have a haploid(n) number of chromosomes and body (somatic) cells have a diploid (2n) number of chromosomes.

For example in humans our somatic cells have 46 chromosomes. However, the gametes( sperm or egg) of humans have 23 chromosomes

Answer 4

Gametes have gone meiosis, this kind of cell division halves the number of chromosomes. This is accomplished by diving the cell twice without replicating the DNA a second time.

Answer 5

Reducing the number of chromosomes is meiosis.
