Analyze the outcome of mitosis
Mitosis is a process of cell division that results in two genetically identical daughter cells. Since the parent cell is diploid, the resulting cells are also diploid. Thus, mitosis begins with 1 cell and ends up with 2 diploid cells.
Determine the phase of crossing over
Crossing over occurs when homologous chromosomes pair up to form tetrads. This pairing (synapsis) and subsequent genetic exchange occur during the first prophase of meiosis, which is Prophase I.
Identify the phase where chromatids separate
During cell division, sister chromatids are pulled apart toward opposite poles of the cell. This separation of sister chromatids occurs during Anaphase.
