meiosis
What is Half of the number of chromosomes
The failure of replicated chromosomes to separate is called nondisjunction. This can lead to an abnormal number of chromosomes in daughter cells during cell division, which can result in genetic disorders such as Down syndrome.
The homologus chromosomes form a four, quad, and in telephase the 'homologus' chromosomes separate in half. Then, they separate and make 2 diploid cells.
They are separated in Anaphase I of Meiosis I.
Mitosis and Meiosis
What is Half of the number of chromosomes
Both autosomes and sex chromosomes separate during mitosis./ Somatic chromosomes separate during mitosis with same number as in the parent cell.
During meiosis, the homologous chromosomes separate and go to different gametes.
The term for when chromosomes fail to separate during cell division is called nondisjunction.
The failure of replicated chromosomes to separate is called nondisjunction. This can lead to an abnormal number of chromosomes in daughter cells during cell division, which can result in genetic disorders such as Down syndrome.

The homologus chromosomes form a four, quad, and in telephase the 'homologus' chromosomes separate in half. Then, they separate and make 2 diploid cells.
At the end of meiosis I, the chromosomes are duplicated (sister chromatids) and homologous chromosomes separate. At the end of meiosis II, the sister chromatids separate, resulting in four haploid daughter cells each with a single set of chromosomes. Meiosis II is similar to mitosis in terms of chromosome behavior as the sister chromatids separate.
They are separated in Anaphase I of Meiosis I.
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.
