Consider the genealogy of three sequences from a population of N = 5000 diploid individuals. Assume the mutation rate is μ= 10-5 per sequence per generation.
When we move backwards in time by one generation, what is the probability of… (a) A coalescent event?
(b) A mutation event?
(c) Exactly 1 mutation and no coalescent?
(d) Exactly 1 coalescent and no mutation?
(e) Either a coalescent event or a mutation event?
