WebThe four main types of chromosomal mutations are deletion, inversion, duplication, and translocation mutations. Aneuploidy is when a cell has extra or missing chromosomes. Aneuploidy is the result of nondisjunction, which occurs when homologous chromosomes or sister chromatids do not separate during meiosis or mitosis.
