anaphase 1
anaphase I.
IN THE NUCLEUS OF A CELL.................................
They are separated in Anaphase I of Meiosis I.
homologous chromosomes separate.
Anaphase I, and then again in Anaphase II--two seperations occur in meiosis.
Nondisjuction occurs when the homologous chromosomes fail to separate.
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.
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.
During meiosis, the homologous chromosomes separate and go to different gametes.
The haploid number (n) of an individual is determined by the number of homologous pairs of chromosomes that separate during meiosis. If four homologous pairs separate during anaphase I, that means there are four pairs of chromosomes, resulting in a haploid number of n = 4. Therefore, the total number of chromosomes in the diploid (2n) state would be 8.
