Which 2 stages of meiosis are the same as mitosis?
Explanation: So everything in meiosis 2 (prophase2 ,metaphase 2, anaphase 2, telophase 2) is same as mitosis. The only difference would be that there are 2n chromosomes in metaphase but only n chromosomes in meiosis 2 since homologous chromosomes separate in meiosis 1.
Which phase of meiosis 1 is most similar to the comparable phase in mitosis?
Prophase I sets the stage for the reductive division. Meiotic cells have an interphase period similar to mitosis with G1, S, and G2 phases. This is followed by prophase I in which homologous chromosomes align along their entire length.
Which stage of meiosis are most closely resembles mitosis?
Meiosis II closely resembles mitosis. The two daughter cells move into this phase without any further chromosome duplication. The sister chromatids are pulled apart during this division. A total of four haploid daughter cells are produced during the course of meiosis II.
What’s the difference between anaphase 1 and 2?
Anaphase 1 and anaphase 2 are two phases in the meiotic division of cells which produces gametes during the sexual reproduction. The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated during anaphase 2.
Which of the following stages of meiosis is most similar to anaphase of mitosis?
Meiotic anaphase II is similar to the anaphase in mitosis. Both mitotic anaphase and meiotic anaphase II involves the separation of sister chromatids towards the opposite poles of the cell.
Is meiosis 1 or 2 more like mitosis?
When the tetrad is broken up and the homologous chromosomes move to opposite poles, the ploidy level is reduced from two to one. For this reason, meiosis I is referred to as a reduction division. There is no such reduction in ploidy level during mitosis. Meiosis II is much more similar to a mitotic division.
Why is meiosis 2 most like mitosis?
The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.
Does meiosis 2 occur after fertilization?
At fertilization, the secondary oocyte completes meiosis II to form a mature oocyte (23,1N) and a second polar body.
