During meiosis, sister chromatids separate during anaphase II, resulting in four haploid daughter cells with different genetic material. This process ensures genetic variation in the offspring.
They separate in anaphase and become chromosomes in new daughter cells
Sister chromatids are attached at the centromere and are aligned at the metaphase plate by the mitotic spindle which will also separate the sister chromatids from one another.

Are sister chromatids still attached in prophase 2 of meiosis?
No, sister chromatids are separated during anaphase of meiosis I. In prophase II of meiosis, each chromatid (now called a chromosome) pairs with its homologous chromosome, but they are not connected as sister chromatids.
What happens in meiosis I that does not occur in meiosis I I?
DNA is copied.
How do you chromosomes at end of meiosis i compare with the chromosomes at end of meiosis ii?
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.
What is the difference between sister and non sister chromatids?
Sister chromatids are two identical copies of a single chromosome that are joined together by a centromere and are produced during DNA replication. Non-sister chromatids are chromatids belonging to different homologous chromosomes that can undergo genetic recombination during meiosis.
At what stage does sister chromatid separation occur by mitosis and meiosis?
Sister chromatid separation occurs during anaphase of mitosis and anaphase II of meiosis. In mitosis, sister chromatids are separated to opposite poles of the cell, while in meiosis II, sister chromatids are separated to produce four haploid daughter cells.
Are sister chromatids still attached in prophase 2 of meiosis?
No, sister chromatids are separated during anaphase of meiosis I. In prophase II of meiosis, each chromatid (now called a chromosome) pairs with its homologous chromosome, but they are not connected as sister chromatids.
When during meiosis do sister chroamtids separate?
Sister chromatids separate during anaphase II of meiosis.
What happens in meiosis I that does not occur in meiosis I I?
DNA is copied.
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

Sister chromatids are two identical copies of a single chromosome that are joined together by a centromere and are produced during DNA replication. Non-sister chromatids are chromatids belonging to different homologous chromosomes that can undergo genetic recombination during meiosis.
Copies of chromosomes liked together at their centromeres at the beginning of meiosis are called what kid of chromatid?
At the beginning of meiosis, copies of chromosomes linked together at their centromeres are called sister chromatids. These sister chromatids are duplicated copies of a single chromosome and are held together by proteins called cohesins.
Crossovers between non-sister chromatids during meiosis form?
chiasma
At what stage does sister chromatid separation occur by mitosis and meiosis?
Sister chromatid separation occurs during anaphase of mitosis and anaphase II of meiosis. In mitosis, sister chromatids are separated to opposite poles of the cell, while in meiosis II, sister chromatids are separated to produce four haploid daughter 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.
Which meiosis better mirrors the mitosis process?
Meiosis I better mirrors the mitosis process because during this stage the homologous chromosomes separate, similar to the way sister chromatids separate during mitosis. Meiosis II, on the other hand, involves separating sister chromatids, which is not seen in mitosis.
The separation of the sister chromatids marks the beginning of what structure?
The separation of sister chromatids marks the beginning of anaphase in mitosis or meiosis. During anaphase, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
