Question 2 of 2 4.0 Points Which of the following forces can either add or help maintain, but not decrease, the genetic variation in a population? Pick ALL that apply: Mark for Review What's This? Part 2 of 7 - Sea Urchins You are studying a population of 10 haploid sea urchins. 1 urchin is white (due to the W allele at a particular color locus) and 9 are purple (due to the P allele at that locus). Even though each of the urchins produce tons of offspring, only 10 can survive in every generation. Assume that the W and P allele are equivalent and there is no selective advantage to having either one of these alleles.

    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.
