A student has a group of corn plants with long stalks, and a group of corn plants with short stalks. She crosses the long stalk and short stalk plants. The resulting generation of corn plants all have short stalks. Based on this experiment, what can the student determine about the alleles for stalk length? A. Short stalks must be recessive, because the short stalk trait was hidden in some of the offspring.

B. Short and long stalks are both dominant, because both traits were present in the parent plants.

C. Short stalks must be dominant, because the short stalk trait covered up the long stalk trait in the offspring.

D. Long stalks must be dominant, because the long stalk trait was present in one of the parent plants.

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).
