Neighbor-joining tree of 63 Saccharomyces cerevisiae strains. The tree was constructed based on the 101,343 segregating sites identified in the surveyed strains. Branch lengths are proportional to the number of the 101,343 segregating sites that differentiate each pair of strains. Font color of strain name denotes geographic origin and circle color denotes ecological niche as specified in the key.

Decay of linkage disequilibrium as a function of distance. Averages of pairwise LD measures r2 (black circles) and D' (open circles) are plotted for each bin of distances between pairs of SNPs. The LD values were corrected for finite-size effects by subtracting the average value computed for a random subset of pairs of SNPs located on different chromosomes.

Population structure of 63 Saccharomyces cerevisiae strains. Cluster results from a structure analysis on 101,343 segregating sites identified in the 63 surveyed strains. Structure implements a Bayesian model-based clustering algorithm that attempts to identify genetically distinct subpopulations based on patterns of allele frequencies15. Each strain is represented by a single vertical bar, which is partitioned into K colored segments that represent the strain’s estimated ancestry proportion in each of the K clusters.
