Chromosomal mutations are changes in the normal structure or number of chromosomes. Changes in chromosome structure can result f

rom errors in meiosis or from exposure to radiation or other damaging agents. Certain changes in chromosome number can result from nondisjunction during either meiosis or mitosis. Both structural mutations and nondisjunction can play a role in trisomy 21, commonly known as Down syndrome.
