Maturing oocytes are arrested in prophase I of meiosis I and lie dormant within a protective shell of … Webthe metaphase plate during Metaphase II. During Anaphase II, the sister chromatids separate and move to opposite poles. In Telophase II, the nuclear membrane reforms and cytokinesis occurs. Comparing Mitosis and Meiosis:--Mitosis occurs in somatic cells; meiosis occurs in germ cells.--Mitosis has one round of division; meiosis has two rounds.

With 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 ... WebMeiosis This is a special sequence of 2 cell divisions that produces haploid gametes from diploid germline cells. It starts with a diploid cell that has undergone chromosomal DNA replication: 2N chromosomes, 4X DNA content. Two successive divisions, with no additional DNA replication, results in 4 haploid gametes: 1N chromosomes, 1X DNA content. how late is kroger open today

Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase, which is also called the first gap phase, is the first phase of the interphase and is focused on cell growth.
