Tetrad in Meiosis Definition & Formation - Study.com
WebIn meiosis Each pair of chromosomes—called a tetrad, or a bivalent—consists of four chromatids. At this point, the homologous chromosomes exchange genetic material by the process of crossing over ( see linkage group). The homologous pairs line up along the midline of the cell in metaphase I and then separate in anaphase I,… Read More WebHowever, in meiosis, nuclear division occurs twice during Meiosis I and Meiosis II, and each stage of meiosis is comprised of four phases: meiosis I (prophase 1, metaphase 1, anaphase 1, and telophase 1) and meiosis II (prophase 2, metaphase 2, anaphase 2, and telophase 2).
