Mark for Review What's This? Question 3 of 5 4.0 Points In which of the following examples would you expect natural selection to dominate over genetic drift? Pick ONE BEST choice: A. A population of 70 unicorns has an even mix of red, orange, yellow, green, blue, indigo, and violet coat colors. There is no selection on coat color and they mate randomly, but after a few dozen generations, there are 35 red and 35 yellow unicorns. B. There are 10,000 algal cells in a pool. One of them gets a unique C G mutation that has no effect on function. In the next generation, this cell has 2 offspring that survive (both with the mutation) and the population size is still 10,000. C. There are 100 biologists on Biology Island. 4 have red hair. One biologist accidentally infects everyone with Ebola, but 3 biologists survive, including one redhead. There is no evidence that red hair correlates with disease resistance. D. There are a bunch of beetles. Only one is blue. You accidentally step on it, but not because it’s blue. Sadly, now there are no blue beetles. E. Liberty the moose and her eight offspring are far more hardy in the winter than most moose, and her local population of 1000 moose goes through a prolonged period of very cold winters in which many moose die. During this period, you find that the fraction of the population that consists of the descendants of Liberty and her offspring rises faster than what you would expect by chance alone, and after 5 years, a fifth of the new population of 500 individuals now consists of the descendants of Liberty.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
