#Part-A Aptitude & General Biotechnology
  1. chromosome may be lost in the course of mitosis or meiosis

  2. small chromosome generated by a Robertsonian translocation may be lost in mitosis or meiosis,

  3. may arise through nondisjunction, the failure of   homologous chromosomes or sister chromatids to separate in meiosis or mitosis

  4. inversion of chromosomal segment including centromere
