What else can I help you with?
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.
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.
Is there a replication step before meiosis ii?
Yes, there is no replication step between meiosis I and meiosis II. The DNA remains in a duplicated state from the end of meiosis I and goes directly into meiosis II, where the sister chromatids are separated.
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.
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
What are the names of the two different types of meiosis?
The two types of meiosis are meiosis I and meiosis II. Meiosis I involves homologous chromosomes separating, while meiosis II involves sister chromatids separating.
Is there a replication step before meiosis ii?
Yes, there is no replication step between meiosis I and meiosis II. The DNA remains in a duplicated state from the end of meiosis I and goes directly into meiosis II, where the sister chromatids are separated.
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.
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.
Which phase of meiosis do sister chromatids pull apart and move to opposite ends of the cell?
Sister chromatids are pulled apart from each other during the anaphase II stage of meiosis II. From there the chromatids are taken to opposite poles of the cell and create two haploid 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 what does the sister chromatids of chromosomes separate and four haploid daughter cells are formed?
During meiosis, the sister chromatids of chromosomes separate into different cells, ultimately resulting in four haploid daughter cells.
