If you were to treat sperm precursor cells with an agent that completely destroys microtubules (and ensures that they don't reform) at the start of metaphase I, how would this affect meiosis?

A. This would prevent kinetochores from forming on either side of the centrosome during meiosis I.
B. Meiosis I would be interrupted, but meiosis II would proceed normally, since microtubules are not required during this stage.
C. Homologous chromosome pairs would not line up at the cell's center, and the rest of meiosis would not proceed normally.
D. This would only affect the separation of homologous chromosomes during anaphase I, but would not cause any changes to telophase I or subsequent cell division.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
