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 … WebApr 8, 2024 · Initially, taking as example a 2n somatic cell, ploidy increases to 4n (duplication of DNA) during interphase. During meiosis I, since homologous chromosomes are separated, ploidy falls to 2n (the original number) and then during meiosis II ploidy finally falls to n in the resulting daughter cells. Ploidy reduction does not occur in mitosis.
WebFinally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one. Despite this fact, many of the other events of meiosis are similar to those that occur in mitosis. WebThe main differences between mitosis and meiosis occur in meiosis I. In meiosis I, the homologous chromosome pairs become associated with each other and are bound together with the synaptonemal complex.
