During oogenesis, meiosis results in:A) four equally sized cells that stop dividing in meiosis 1B) 2 equally sized cells, but only one that is typically fertilizedC) 2 equally sized cells that are both typically fertilizedD) 2 or 3 small cells and one large cell that develops further if fertilized

Which of the following cells are haploid? (a) (b) spermatogonium ova (c) (d) oogonium somatic cell

Meiosis is an important cellular process for organisms that reproduce sexually. 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…

3) At the completion of meiosis, how many sets of chromosomes does each daughter cell contain?     1     2     3     4   4) Imagine that a cell within a tissue is expressing a protein that leaves the cell and can “signal” to other cells. Which cells will respond?   A) Cells that are within range of the signaling molecule and have protein receptor that binds the signaling molecule   B) Cells that are within range of the signaling molecule   C) Cells that are within range of the signaling molecule and are expressing their own signaling molecules   D) Cells that are within range of the signaling molecule and are the same type of cell
