In animals, this event aims to form gametes (gametic meiosis) while in plants it forms spores (sporic meiosis). Subdivided into meiosis 1 and 2, it is in the first stage, specifically in Prophase 1, that crossing-over occurs (also called exchange or recombination). Leptotene, zygotene, pachytene, diplotene and diakinesis are sub-stages explored in this class, as well as terms such as chiasma and crossing-over. ⭐ Facebook: / biologiaprofgui ⭐ Instagram: / gogoulart - @gogoulart
