The phenomena that occur when the human organs chromosomes do not separate during meiosis is known as nondisjunction.
Explanation:
- The phenomenon of nondisjunction can take place either during meiosis I or meiosis II.
- In case the nondisjunction occurs during anaphase I of meiosis I, which means that at least one pair of homologous chromosomes are in union and separatation of them has not taken place.
- Nondisjunction results in the formation of Aneuploidy, which means there will be pairs of homologous chromosomes which fails to separate during the process of meiosis.
