During anaphase II of meiosis, sister chromatids separate and move towards opposite poles of the cell. This results in the formation of haploid daughter cells with a unique combination of genetic material.

When does independent assortment occur in meiosis?
Independent assortment occurs in meiosis during metaphase I when homologous chromosomes align randomly at the metaphase plate. This allows for different combinations of alleles to be present in the gametes produced.
What stage of meiosis is the chromosome number reduced?
In Anaphase I
In which phase do centromeres uncouple sister chromatids are separated and two new chromosomes move to opposite polls of the cell?
This occurs during the anaphase phase of mitosis. In anaphase, the microtubules shorten, pulling apart the sister chromatids at their centromeres. The separated chromatids are then pulled to opposite poles of the cell by the spindle fibers.
Segregation of alleles occurs during?
Segregation of alleles occurs during meiosis, specifically during the separation of homologous chromosomes in anaphase I. This process ensures that each gamete receives only one copy of each gene, leading to genetic diversity in offspring.
In what phase does the movement of individual chromosomes towards opposite poles occur?
The movement of individual chromosomes towards opposite poles occurs during the anaphase stage of mitosis. During anaphase, the sister chromatids separate and are pulled to opposite ends of the cell by the spindle fibers.
Does cytokinesis occur during anaphase?
No, it occurs after telophase, which is after anaphase.

What stage of meiosis is the chromosome number reduced?
In Anaphase I
During what phase do the two copies of each chromosome separate from each other and begin to move to opposite poles?
This occurs during anaphase.

What forms during anaphase?
chromosomes and the mitotic spindles are formed during anaphase
What process does non disjunction occur in?
Nondisjunction occurs during anaphase, usually when referring to meiosis, when a tetrad fails to separate.
What are the names of the four phases of mitosis?
The four phases of mitosis are prophase, metaphase, anaphase, and telophase.
When do sister chromatid separate during meiosis?
The sister chromatid separate during anaphase II in meiosis. During anaphase I homologous chromosomes get separated.
