Genome-wide plot of the wild strain origins of genomic content in the mixed and selected populations based on allele frequencies of IDtags. DNA from eight wild strains was found in the mixed strains (see Fig. S4 for content from wild strains 8874, 3200, and 3199, which were sampled at low frequency). Diversity in the spore strains (1, 2, and 3) came from only four wild strains, whereas nine wild strains were represented in the growth strains (a–c). Frequencies for each population range from 0 to 1
