Enrichment of shared alternate alleles in common ecological niches. a Schematic of a phylogeny in which the alternate (RM11) allele occurred twice, and only in the fermentation niche. b Fraction of variants segregating in the SGRP collection for which the alternate allele occurs only in strains from same ecological niche (blue: all variants; red: only synonymous variants), for loci with the alternate allele occurring (left) in two strains or (right) in three strains; the neutral expectation was calculated by 50 independent simulations; the mean of the simulations and the results of each simulation are shown in gray and with black dots, respectively. p values by permutation test.
