How do anaphase i and anaphase ii differ
WebHow does anaphase II differ from anaphase I? At the end of anaphase II, how many chromatids are on each side of the cell? After cytokinesis, how many cells have been formed from the parent cell? Are all of the cells the same size? The original parent cell is called diploid because it contains a complete set of homologous chromosome pairs. WebConcept explainers. Article.

However, in meiosis I homologous chromosomes must be held together in metaphase I, before these ties are swiftly broken during anaphase I.
WebAug 8, 2024 · During anaphase, sister chromatids (or homologous chromosomes for meiosis I), will separate and move to opposite poles of the cell, pulled by microtubules. In nondisjunction, the separation fails to occur causing both sister chromatids or homologous chromosomes to be pulled to one pole of the cell. WebWith the stages in meiosis I, the primary difference lies in prophase I, which is much longer than either its meiosis II or mitosis counterparts, and is in fact the stage a cell is in for 85%-95% of the time spent in meiosis. This is due to being the stage in which crossing-over, the defining event of meiosis I, occurs. Prophase I
