The ability to perceive a bitter taste from certain chemicals, including ptc, has been linked to certain alleles. which of the answer choices would provide an explanation for the fact that almost all nonhuman primates have the "taster" phenotype, whereas the human population has a significant percentage of "nontaster" phenotypes?
a. the advantage to being able to taste bitter compounds would keep you from eating poisonous compounds, an advantage not needed in the human population anymore. b. the advantage to not being able to taste bitter compounds means that humans are more likely to eat vegetables and hence live longer than nonhuman primates. c. nonhuman primates only eat foods that are not bitter, so the phenotype of tasting bitter compounds was not selected against. d. humans needed the ability to not taste bitter compounds, so the mutation happened.

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).
