Both meiosis and mitosis occur in different stages including prophase, metaphase, anaphase etc but meiosis occurs in two series of division processes called meiosis I and meiosis II.
In prophase I of meiosis, homologous chromosomes, which are similar but non-identical chromosomes from male and female parents pair to form tetrad or bivalent. This pairing of homologous chromosome is unique and peculiar to MEIOSIS but never mitosis.
