A group of students were studying dandelion cells. The students observed that some of the cells were undergoing meiosis to produce seeds and some were undergoing mitosis to produce flowers and leaves. When examining the cells, which of the following would the students observe in both the cells undergoing meiosis and the cells undergoing metosis? I.) One round of DNA duplication occurs before cell division starts.
II.) The resulting cells are genetically identical to each other.
III.) Sister chromosomes from a synapsis where chiasmas form and cross-over occurs
IV.) Sister chromatids cling together due to chromosome cohesion until enzymes cleave the bonds.
