WebMeiotic division I is far more complex and requires much more time than either mitosis or meiotic division II. Even the preparatory DNA replication during meiotic division I tends to take much longer than an ordinary S phase , and cells can then spend days, months, or even years in prophase I, depending on the species and on the gamete being formed ( … Web4 sep. 2024 · Meiosis involves two nuclear and cell divisions without interphase in between, starting with one diploid cell and generating four haploid cells.
