What is Meiosis?
Meiosis is a process that produces haploid cells, or cells with only half of the chromosomes of the original cells. In creatures
that sexually reproduce, haploid cells from the mother and the father combine to form a diploid cell which develops into a new
organism.
How Does it Work?
Meiosis begins in cells that have undergone the G1, S, and G2 phases (the process of interphase). This means that the
cell has already grown and copied its DNA. In humans, for example, the cell would start with 46
chromosomes each consisting of two chromatids. Meiosis happens in two stages:
Meiosis I: Cell divides to form two cells with 23 chromosomes, each consisting of two chromatids.
Meiosis II: Both cells divide into another two cells each containing 23 chromosomes consisting of 1 chromatid.
