1. Consider a locus that has all four nucleotides segregating in the population with frequencies of A=0.5, C=0.1, G=0.3, T=0.1. Assuming all nucleotides have equal fitnesses (i.e., the variants are selectively neutral), (a) What is the probability that G will eventually be lost from the population? (b) What is the probability that either C or G will eventually be fixed? (Note: I'm asking for a single probability of C-or-G, not multiple probabilities)
