Two lab partners (A and B) are shown this diagram of a meiotic cell and asked to identify its phase. Partner A believes that this cell is in prophase of the first meiotic division. Partner B believes that this cell has moved past prophase of meiosis I and is in a later phase of meiosis. Which partner is correct, and what evidence accurately would defend their belief? Partner A is correct. The chromosomes have clearly replicated during interphase and are beginning to decondense into chromatin. O Partner A is correct. The nuclear membrane is beginning to re-form and centrioles are beginning to migrate to opposite poles of the cell. Partner B is correct. Homologous chromosomes are no longer paired together, so the cell must be in first phase of meiosis II, not meiosis I. O Partner B is correct. The cell plate is beginning to form between the two centrioles, indicating the cell is actually in later phase of…arrow_forwardGive typing answer with explanation and conclusionarrow_forward
