Biological purpose of meiosis
WebMeiosis is the process of cell division which gives rise to gametes. For the most part, meiosis is very similar to mitosis. Gametes are the sperm and egg. Gametes in most organisms are referred to as the sperm (for males) and the egg (for females). During fertilisation they join to form a zygote, which then divides by mitosis to produce more ... WebMeiosis (/ m aɪ ˈ oʊ s ɪ s / (); from Ancient Greek μείωσις (meíōsis) 'lessening', since it is a reductional division) is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome ().
