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 … WebThe meiotic spindle is a huge structure formed by long proteins known as microtubules on either side, as well as pole, of the cell. It is responsible for the division of the cell. Between prophase I as well as metaphase I, paired pairs of homologous chromosomes form tetrads, which are arranged in a hexagonal pattern. Reference
