Home Part 1-Rattlesnake Evolution In a South Dakota, a new phenotype of rattlesnake is showing up, with “curly-Q” tails. These snakes do not have the ability to make the rattling noise that we associate with rattlesnakes, In a hypothetical situation where the ability to rattle is a single gene trait, the curly-Q tail allele is represented by To, and the n (ror) depending on their genotype. You recorded rattlesnake phenotypes over the course of several generations, trait also shows incomplete dominance, snakes rattle normally (T T), very quietly (TTo), or not at all which followed the pattern shown in the graph below. Rattlesnake Rattle Phenotypes over 7 generations 0.8 0.6 no rattle soh rattle 3.4 0.2 2 0.1 Generation Number A. What is the genotype of the most successful rattlesnake phenotype? If this pattern is a result of natural selection, what type of natural selection (directional, stabilizing, or disruptive) is taking place in this population of rattlesnakes? B. C. Explain in words and fill in the simplified graph below with the lines showing the type of natural selection you chose in B above. The dotted line shows the distribution of the original population at generation zero. The x-axis is labeled for you. Label the Y-axis and title your graph. No rattle Rattle Soft rattle Give an example of a selective pressure that could lead to the pattern that you see in this snake population. Explain how the selective pressure you chose would result in this pattern. D.
