Meiosis

Hello Hamiltons, this is a page to help you better understand Meiosis.

Meiosis is the type of cell division that occurs in sex cells. It takes place in the ovaries and testes in humans. Before it begins, DNA needs to replicate. The end result of meiosis is known as a gamete. A gamete for males is a sperm cell and one for females is an egg cell. Also, it is a special kind of cell division where four cells are produced; each cell has only half of the original number of chromosomes(haploid).

Meiosis is divided into 2 stages: Meiosis 1 and meiosis 2.

Meiosis takes a cell that contains two copies of each chromosome, and it divides it up into four gametes each containing one copy of each chromosome.

Down Syndrome is closely related to meiosis, as it is during meiosis that a non-disjunction can occur. A non disjunction on chromosome 21 is the cause of down syndrome.

Meiosis is special kind of cell division where four cells are produced; each cell has only half of the original number of chromosomes. meiosis produces the sex cells. eggs and sperm. On the left is what Meiosis is supposed to look like when it happens properly. On the right is what happens when nondisjunction occurs in Meiosis.
