Recap: o Inbreeding F=probability that Z alleles came from the same ancestor (IBD) A1A1=p2(1-F)+pF Under settling at equilibrium, F=1 all are homogenous o Drift-sampling error What individuals contribute to gene pool based on differential survival/reproduction If no drift, in the next population, the frequency of alleles in gene pool=frequency of alleles in next generation

    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.

    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.
