Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.
Then, why does meiosis result in haploid cells?
After mitosis two identical cells are created with the same original number of chromosomes, 46. Haploid cells that are generated through meiosis, such as egg and sperm, only have 23 chromosomes, because, remember, meiosis is a "reduction division." Makes all cells other than gametes.
Why are gametes haploid and not diploid?
It involves joining together haploid gamete cells from each parent with half the normal number of chromosomes to make a new cell containing both parents' genetic material. This is a diploid zygote. The cells from each parent that combine to form the zygote are called gametes.
Why is it necessary to have haploid gametes?
Haploid cells produced during meiosis, which are smaller in size compared to the gamete and will disintegrate. Why is it important that gametes are haploid cells? It is important that chromosomes are haploids, because when the sperm and the egg fuse together the cell will have 46 chromosomes.
