This diploid cell undergoes meiosis (chromosomes replicate prior to meiosis). Which of the cells below represent(s) a possible way that the replicated chromosomes could line up in metaphase I of meiosis? Assume that no crossing-over occurs. Bb В Б b-b bobB,B Bb Bb РА b-B БУБ В В X

6) The plant Haplepoppus gracilis is diploid (2n = 4). Inside each cell (represented here by the oval) there are four total chromosomes: one long pair (represented by "A" and "a") and one short pair (represented by "B" and “b"). The following diagrams represent possible anaphases of this cell during meiosis or mitosis. The lines represent chromosomes/chromatids being pulled to either the north or south pole of the cell, and the vertex of each "V" represent the centromere which would be attached to kinetochore microtubules. For representative cells 1– 12, say if the diagram represents a cell in anaphase I of meiosis I, anaphase II of meiosis II, anaphase of mitosis, or shows an impossible situation. If the situation is impossible, explain why. い。 VA Vb VA VB VV. V b Va VB VAVA Vo VB ^^ ^ が VaVA Vo VB くs

What would be the number of chromosomes and chromatids for a cell (2n=4) in each phase (S-phase, Prophase, Metaphase, Anaphase and Telophase/Cytokinesis) of Meiosis I and II?

Choose the phase of meiosis in column 2 that best matches each event in column 1.                                                                                                         one haploid set of replicated chromosomes at each spindle pole                                                                                                         genetic recombination events take place                                                                                                         shortest stage                                                                                                         aligning of bivalents in the center of a spindle                                                                                                         one haploid set of unreplicated chromosomes at each spindle pole                                                                                                         aligning of monovalents in the…

In Pop-Bead Meiosis, you start with 4 chromosomes: 1 big red, 1 little red, 1 big yellow, and 1 little yellow. After meiosis I, how many chromosomes will be present in each daughter cell? How many “big” chromosomes per cell? How many “little” chromosomes per cell?
