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?
In the context of cell division, chromosomes will aline in the middle of the cell during metaphase, then during anaphase they are pulled apart into two daughter cells by centrioles. I wouldn't say they are ever on opposite poles, also considering that there is no directionality of a cell.
Does cytokinesis occur during anaphase?
No, it occurs after telophase, which is after anaphase.
Does chromosomes separate during anaphase unique to mitosis and not a part of meiosis?
Chromosome separation occurs during both mitosis and meiosis, but the processes are distinct. In mitosis, sister chromatids are separated during anaphase, resulting in two identical daughter cells. In meiosis, homologous chromosomes separate during anaphase I, and sister chromatids separate during anaphase II, leading to four genetically diverse gametes. Thus, while separation occurs in both processes, the context and outcomes differ.

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.

Is anaphaselor1 or anaphase 2 in meiosis more analogous to anaphase in mitosis?
Anaphase I of meiosis is more analogous to anaphase in mitosis than anaphase II. In anaphase I, homologous chromosomes are separated and pulled to opposite poles, similar to how sister chromatids are separated during mitotic anaphase. In contrast, anaphase II involves the separation of sister chromatids, which is akin to what occurs in mitosis but happens after a reductional division in meiosis. Thus, the mechanisms and outcomes of anaphase I align more closely with those of mitosis.
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.
