These errors are known as nondisjunction errors. Although cell division is almost a perfect process, errors can happen during the chromosomal disjunction at a very small error rate. It is referred to as chromosomal disjunction. During the cell division processes, homologous chromosomes and sister chromatids are separated without errors to produce daughter cells with the same number of chromosomes or half the number of the chromosomes. Genetically identical diploid cells are produced by mitosis and gametes (haploid) with half chromosome sets are produced by meiosis. There are two major cell division processes known as mitosis and meiosis. Key Difference – Nondisjunction in Meiosis 1 vs 2Ĭell division is a vital process in multicellular organisms as well as in unicellular organisms.
