What is nondisjunction and why is it harmful?
Nondisjunction is the failure of a homolog to separate during meiosis causing trisomy (an extra chromosome) or monosomy (a missing chromosome), it can be harmful because it is a mutation that can cause many devastating disease, for example nondisjunction of the 21st chromosome causes down syndrome, another example of nondisjunction being harmful, is nondisjunction of the sex chromosomes, causing Turner's or Klinefelter's syndrome two very devastating diseases.
