How many division occur during meiosis
Web6. During interphase preceding meiosis, each chromosome replicates itself and becomes two chromatids joined at the centromere. These identical chromatids are known as sister chromatids. During the first division of meiosis, pairing of homologous chromosomes takes place. The structure formed is called a bivalent. When paired in this way non-sister … WebFinally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one.
