Summary of meiosis 1

WebMeiosis is how sex cells reproduce, dividing their chromosomes by half to create four haploid cells that are distinct from the original cells that birthed them. Meiosis has two different phases: meiosis one (meiosis I) and meiosis two (meiosis II). These phases are further divided into sub-phases, and metaphase one is a sub-phase of meiosis one ... WebMeiosis ( / maɪˈoʊsɪs / ( listen); from Ancient Greek μείωσις (meíōsis) 'lessening', since it is a reductional division) [1] [2] is a special type of cell division of germ cells in sexually …
