WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a tetrad, which is made up of four chromatids (two sister chromatids per chromosome).

WebThe human body uses both meiosis and mitosis as methods of cell division. A single cell splits into two identical daughter cells during the process of mitosis, each of which has the same number of chromosomes as the parent cell. It takes place in somatic cells, which are the body's non-reproductive cells, and is in charge of growth and repair. WebThe variation introduced into the reproductive cells by meiosis appears to be one of the advantages of sexual reproduction that has made it so successful. Meiosis and fertilization alternate in sexual life cycles. The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell.
