chromosomes appear as packets of four chromatids during anaphase. This is when the chromatids start to move and separate in preparation of the creation of four cells.

What division of meiosis splits chromosomes?
In anaphase I of meiosis, the homologous pairs of chromosomes separate. Due to DNA replication and crossing over during prophase I, these chromosomes consist of a pair of non-identical sister chromatids. During anaphase II of meiosis, the sister chromatids separate into individual chromosomes.
During meiosis the chromatids become daughter chromosomes during which stage?
Anaphase 2
What is a pachytene?
A pachytene is the third prophase of meiosis, during which the chromosomes shorten and divide into four chromatids.
What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
Chromatids line up along the equator?
The chromatids line up at the equator of the cell during the metaphase of meiosis. After which the chromatids separate to form individual chromosomes.
Do chromosomes have one or two chromatids as they move toward the poles during anaphase of meiosis one?
Two
In mitosis or meiosis do doubled chromosomes pair to form tetrads?
Tetrads form during meiosis. Tetrad refers to the four chromatids of homologous chromosomes.These are present during Prophase.
What is a process in which homologous chromosomes exchange portions of their chromatids during meiosis?
the process in which homologous chromosomes exchange portions of their chromatids during meiosis is the definition of the term "Crossing Over"
When are the sister chromatids of each duplicated chromosomes separated?
Chromosomes separate during the anaphase stage of meiosis or mitosis. During this stage the chromosomes move to the opposite ends of the cell.
What are nondisjunction genes?
Nondisjunction is the failure of homologous chromosomes or chromatids to segregate during mitosis or meisos with the result that one daughter cell has both of a pair of parental chromosomes or chromatids and the other has none. An example is Trisomy 21, which is also called Down's Syndrome. This person has 3 chromosome #21.Nondisjunction of genes occur during meiosis I when homologous chromosomes fail to separate or during meiosis II when there is unequal distribution of chromosomes. This leads to aneuploidy.
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.
The chromosomes separate and move in opposite directions during?
IN Mitosis, the Siter chromatids separate in anaphase. IN Meiosis, the tetrads separats in anaphase I and the siter chromatids separates in anaphase II
