Webb17 mars 2024 · In meiosis, prophase serves as the initial stage of the first of the two divisions. In this prophase (sometimes identified as prophase I), the homologous paternal and maternal chromosomes condense in the nucleus of the diploid cell. Each pair of chromosomes—called a tetrad, or a bivalent—consists of four chromatids. WebbMitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle. Interphase & mitosis.
