Differbetween
The main difference between anaphase I and anaphase II is that anaphase I occurs in a diploid cell and anaphase II occurs in a haploid cell. ... In anaphase I, splitting of centromere do not occur whereas, in anaphase II, sister chromatids separate, splitting the centromere.

How does anaphase II differ from anaphase I?
In meiosis, what is the difference between Anaphase I and Anaphase II? In Anaphase 1 , the homologous (same) chromosomes separate to either side of the cell, and the centromere is whole. In Anaphase 2, the sister chromatids separate, and the centromere is split, which causes the chromatids to separate.
What is the difference between anaphase and anaphase 1?
1 Answer. Caprice T. In anaphase 1 in meiosis, homologous pairs are separated but sister chromatids stay joined together. In anaphase 1 of mitosis the sister chromatids do separate.
What happens in both anaphase 1 and 2?
Anaphase1:Homologouschromosomesareseparatedduringanaphase1. Anaphase2:Sisterchromatidsareseparatedduringanaphase2. Anaphase1:Thecentromeresofeachchromosomeinthehomologouspairremainuntouched. Anaphase2:Twosisterchromatidsareseparatedbysplittingthecentromere.
What happens during anaphase II?
In anaphase II, chromosomes divide at the centromeres (like in mitosis) and the resulting chromosomes, each with one chromatid, move toward opposite poles of the cell. Four haploid nuclei (containing chromosomes with single chromatids) are formed in telophase II.
What happen in anaphase 1?
In anaphase I, the homologues are pulled apart and move apart to opposite ends of the cell. The sister chromatids of each chromosome, however, remain attached to one another and don't come apart. Finally, in telophase I, the chromosomes arrive at opposite poles of the cell.
How many chromosomes are at the end of anaphase 1?
These separated sister chromatids are known from this point forward as daughter chromosomes. At the conclusion of anaphase, each end of the cell has an identical and complete set of 46 chromosomes or 23 pairs of homologous chromosomes; they are still diploid.
How do the chromosomes separate in anaphase I?
During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. ... The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
Does DNA replicate before prophase 2?
What Happens During Prophase II? Meiosis II occurs in both daughter cells that were formed during meiosis I. As no DNA replication takes place in this second step of meiosis, the cell division process immediately begins.
How many chromatids are on each side of the cell in anaphase 2?
During anaphase, we now have a total of 16 chromosomes and 16 chromatids – in short, each chromatid is now a chromosome. Similarly, in humans, there are 92 chromosomes present and 92 chromatids during anaphase. These numbers remain the same during telophase.
What's the difference between mitotic anaphase and meiotic anaphase 2?
Anaphase II. Note: Meiosis II is very similar to mitosis. The primary difference is that in meiosis II only one member of each homolog pair is present, whereas in mitosis both are. During anaphase II, the third step of meiosis II, the sister chromatids of each chromosome separate and move toward opposite poles.
What's the difference between Telophase 1 and 2?
During telophase 1, the movement of separated homologous chromosomes is completed to the opposite poles of the cell. During telophase 2, the movement of sister chromatids is completed to the opposite pole of the cell.
