Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion. SCEs can occur during mitosis or meiosis. Homologous chromosomes are important in the processes of meiosis and mitosis. Interphase is the process a cell must go through before mitosis, meiosis, and cytokinesis. These undergo meiosis to form haploid spores. The table below shows the differences between meiosis and mitosis. The zygote undergoes meiosis immediately, creating four haploid cells. In order to understand meiosis, a comparison to mitosis is helpful. Flowering plants generate gametes using a specialized cell division called meiosis. Primordial follicles contain oocytes that are at an intermediate (prophase I) stage of meiosis. The two meiotic divisions are known as meiosis I and meiosis II. Synapsis takes place during prophase I of meiosis. These are specialized reproductive cells called gametes, created in a process called meiosis. Diploids are produced by doubling or fusion of gametes after meiosis. The extra Y chromosome is usually a result of nondisjunction during paternal meiosis II.
