網頁When somatic diploid cells reproduce through mitosis, they produce two identical diploid cells. When cells reproduce through meiosis, they produce two haploid cells called gametes. The gamete cells are not genetically identical because the homologous pairs of chromosomes crossed over to trade some genetic information and also randomly … 網頁Science Biology Compare and contrast meiosis and mitosis. Consider the following factors: Number of times DNA is replicated Number of cell divisions Number of daughter cells produced “Ploidy” of daughter cells Type of cells in which the process occurs Number and genetic make-up of chromosomes in parent cell compared to daughter cells.
4.2 Meiosis and Gametogenesis – Human Biology 2nd edition
Meiosis is divided into meiosis I and meiosis II which are further divided into Karyokinesis I, Cytokinesis I, Karyokinesis II, and Cytokinesis II, respectively. The preparatory steps that lead up to meiosis are identical in pattern and name to interphase of the mitotic cell cycle. Interphase is divided into three phases: • Growth 1 (G1) phase: In this very active phase, the cell synthesizes its vast ar… 網頁Mitosis divides once, meiosis divides twice. Snyapsis occurs in meiosis but not mitosis.Mitosis produces 2 daughter cells that are genetically identical to the parent cell, meiosis produces 4 cells that have genetic variation. 46 chromosomes produced after mitosis but 23 after meiosis. Mitosis produces somatic cells, meiosis produces gametes. season 11 the voice winner

In 1883, it was discovered that, whereas the ... 網頁The cells that are produced by meiosis are genetically unique. Meiosis and mitosis share similarities, but have distinct outcomes.
