Meiosis Comparison
The two different types of meiosis, meiosis I and meiosis II, undergo the same interphase. In this phase, the chromosomes replicate like they do in the S-phase preceding mitosis. In prophase I, the homogonous chromosomes, or two sister chromosomes, come together and condense in a process called synapsis. The four chromatids of the pair of homogonous chromosomes visible under a microscope is called a tetrad. Some of these chromosomes crisscross at the chiasmata, a site where genetic material is exchanged, which help hold the chromosomes together. The genetic traits of the pair of chromosomes are then mixed homogeneously in a process called crossing over. Meanwhile, spindle fibers made of microtubules form as the centrosomes begin to separa
