Changes in genetic divergence and diversity over time for the infant 1157. Panel A, Genetic divergence, as the average number of changes between each time point and the initial population, collected at birth. Panel B, Genetic diversity, as θπ, calculated from the average number of nucleotide differences within a given time point, which correlates with effective population size. The first plot describes the amount of change relative to the initial population and the second one describes the amount of variation within a time point.
