Mejoza (grč. μειόω - meioun = smanjiti, smanjenje). (eng. crossing over). Homologni hromosomi se onda razdvoje na dvije kćerke ćelije, gdje svaka sadrži polovičan broj hromosoma roditeljske ćelije. Početkom anafaze I, upareni homologni hromosomi se razdvajaju, a svaki od njih nosi razmijenjeni segment (putem krosing overa) svog.
