What is Anaphase I?
Anaphase I is a subphase of meiosis I. The process of meiosis begins with the first stage of prophase and then metaphase I, in this stage the homologous pairs of chromosomes align on each side of the equatorial plate ( this is also referred to as metaphase plate) and their centromeres attach with the spindle fibers coming from either pole of the cell. Once this chromosome arrangement is completed then the anaphase I phase begins.
The paired homologous chromosomes would start to separate (into haploid sets) from each other and move toward the opposite poles as the kinetochore microtubules shrink. This stage starts as soon as homologous chromosomes begin separating and ends when the chromosomes reach opposite poles
Difference Between Anaphase I and Anaphase II
The difference between anaphase I and anaphase II lies in the timing of their occurrence during meiosis and the number of chromosomes present in the daughter cells. In anaphase I, homologous chromosomes separate, resulting in haploid daughter cells with duplicated chromosomes, while in anaphase II, sister chromatids separate, producing haploid daughter cells with unduplicated chromosomes.
In this article, we will cover the major difference between Anaphase I and Anaphase II.
