WebFeb 14, 2024 · In prophase I of meiosis, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up at the midway point between the two poles of the cell to form the metaphase plate. The orientation of each tetrad is independent of the orientation of the other 22 tetrads. In which phase in meiosis chromosomes align at the equator? WebThe paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent. What are tetrads in meiosis? meiosis and chromosome role In meiosis. Each pair of chromosomes—called a tetrad, or a bivalent—consists of four chromatids. At this point, the homologous chromosomes …
