18 Coalescents p.18/48 Ancestry of a sample in the population pedigree Time
19 Coalescents p.19/48 Why lineages coalesce under the Wright Fisher model each gene comes from a random copy in the previous generation a chance of 1 out of 2N that another one comes from the same copy hence it takes about 2N generations for two lineages to coalesce
20 Coalescents p.20/48 Sir John Kingman J. F. C. Kingman in about 1983 Currently Emeritus Professor of Mathematics at Cambridge University, U.K., and former head of the Isaac Newton Institute of Mathematical Sciences.

29 Random coalescents from the same population Coalescents p.29/48
30 Two sources of variability (1) Randomness of mutation affected by the mutation rate u can reduce variance of number of mutations per site per branch by examining more sites (2) Randomness of coalescence of lineages affected by effective population size N e coalescence times allow estimation of N e can reduce variability by looking at (i) more gene copies, or (ii) more loci Coalescents p.30/48
31 Coalescents p.31/48 Coalescent with population growth size of population During a population bottleneck there is expected to be a burst of coalescence Down near the root of the tree effects of population size become difficult to see
