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).

You will create a molecular clock model for an arthropod gene. follow these guidelines to make your model: . your timeline will span from 90 million years ago to the present. the common ancestor in your model is an arthropod that lived 90 million years ago. the gene that you'll track codes for a protein in the species venom . the dna sequence youll track contains 10 nitrogen bases. you can choose the order of the bases and where the mutations occur. this gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. to build your model,/ calculate the estimated time period it takes for 1 base pair to mutate. the first time period will only show the common ancestor. at the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences. the first and third descendant species will survive for the rest of the timeline. the second descendant species was extinct 50 million years ago. calculate how long it will take for one full base pair mutation to occur. explain your reasoning by constructing a mathematical equation
