Nondisjunction
Nondisjunction is the term used for when homologous chromosomes fail to separate during meiosis, resulting in an abnormal number of chromosomes in the resulting gametes. This can lead to genetic disorders in offspring due to an incorrect number of chromosomes.
Homologous chromosomes separate during anaphase I of meiosis. This phase occurs after the homologous chromosomes have lined up along the metaphase plate during metaphase I. The separation of homologous chromosomes ensures that each daughter cell receives a complete set of chromosomes.
Anaphase I, and then again in Anaphase II--two seperations occur in meiosis.
During meiosis, the homologous chromosomes separate and go to different gametes.
Nondisjunction occurs when chromosomes fail to separate properly during cell division, resulting in an abnormal number of chromosomes in the daughter cells. This can lead to genetic disorders like Down syndrome, Turner syndrome, and Klinefelter syndrome.

Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
