A failure of homologous chromosomes to separate in meiosis is called nondisjunction. This can result in cells with an abnormal number of chromosomes, leading to genetic disorders such as Down syndrome. Nondisjunction can occur during either the first or second division of meiosis.
They are separated in Anaphase I of Meiosis I.
The failure of a pair of homologous chromosomes to separate properly during cell division is called non-disjunction. This can result in an incorrect distribution of chromosomes into daughter cells, leading to cells with an abnormal chromosome number (aneuploidy). Non-disjunction can result in conditions like Down 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.
Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.

homologous chromosomes separate.
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.
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.
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.
Nondisjuction occurs when the homologous chromosomes fail to separate.
Nondisjunction is the failure to segregate homologous chromosomes or sister chromatids properly during meiosis, leading to an incorrect number of chromosomes in the resulting gametes. This can result in genetic disorders such as Down syndrome.
