During reduction division, specifically in meiosis, the chromatids separate during anaphase II. This process involves the sister chromatids being pulled apart to opposite poles of the cell. As a result, each resulting gamete receives a single set of chromosomes, which contributes to genetic diversity in sexually reproducing organisms. Ultimately, this separation is crucial for producing haploid cells from diploid precursors.

What phase happens when genetic disorder can result when chromatids fail to separate properly?
The phase where genetic disorders can arise from chromatids failing to separate properly is called anaphase, which is part of cell division during mitosis or meiosis. If sister chromatids do not separate, it can lead to aneuploidy, where cells have an abnormal number of chromosomes. This can result in genetic disorders such as Down syndrome or Turner syndrome. Proper chromatid separation is crucial for maintaining genetic stability in daughter cells.
What happens to DNA in anaphase?
The homologous chromosomes (as pairs of sister chromatids) separate to opposite poles of the cell.
What basically happens during a anaphase?
During anaphase, the sister chromatids of each chromosome are pulled apart and move toward opposite poles of the cell. This process is facilitated by the spindle fibers, which shorten and help segregate the chromatids. As the chromatids separate, the cell begins to elongate, preparing for the final stages of cell division. Anaphase is a crucial step in ensuring that each daughter cell receives an identical set of chromosomes.
What happens when mondisjunctuon takes place during cell division?
Mitosis junction, or misjunction, during cell division can lead to chromosomal abnormalities, such as aneuploidy, where cells have an incorrect number of chromosomes. This can occur if sister chromatids or homologous chromosomes fail to separate properly during anaphase. The resulting cells may be nonviable or lead to conditions such as cancer or genetic disorders. Proper checkpoint mechanisms are crucial for preventing misjunction and ensuring genomic stability.
What happens during the first division of meiosis that does not happen in meiosis?
In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids

What happens in telophase II?
Sister Chromatids separate from each other just like mitosis .
What happens to DNA in anaphase?
The homologous chromosomes (as pairs of sister chromatids) separate to opposite poles of the cell.

Anaphase is a crucial step in ensuring that each daughter cell receives an identical set of chromosomes.
What happens during anaphase?
The chromatids are pulled apart.
What happens to sister chromatids in meiosis?
They are separated and pulled to the opposite ends, or poles.
How does the appearance of the chromosome change through division?
first it becomes two chromatids, then during prophase, chromosomes condense from long strands into rod like structures. During METAPHASE paired chromatids align at the cell's equation. Then during ANAPHASE the paired chromatids separate and move to the opposite side of the cell. During TELOPHASE a nuclear membrane forms around each set of chromosomes, and the chromosomes decondense.
Nondisjunction happens in?
It is the failure of chromosome pairs to separate properly during cell division.
What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
What happens to the amount of chromosomes during cell division?
During cell division the chromosomes are copied and they form sister chromatids. Then the mitotic spindle attaches to the sister chromatids and pulls them apart, splitting the nucleus in two. Then the cell goes through cytokenesis and the cell membrane is pinched together in the center, this divides the organelles and the cytoplasm between the two daughter cells.
What happens in the anaphase?
Telophase and then Cytokinesis occurs, where the cells are being split into two.
What happens in a cell during anaphase?
Anaphase: Spindle fibers shorten, the kinetochores separate, and the chromatids (daughter chromosomes) are pulled apart and begin moving to the cell poles. In summery identical sets of chromosomes are moved to opposite sides of the cell.
