Mixed Samples (Long-Term Experiment)

REL606 and REL607 are the Ara- and Ara+ ancestors, respectively. They are isogenic, with the exception of the spontaneous mutation to Ara+ in REL607. Six populations were founded from each of the ancestral clones, giving 12 populations in all. The following table lists the freezer numbers for the mixed-population samples obtained for each population at 500-generation intervals. These mixed samples contain whatever variation was present in the population in that generation. (Note: these are not clonal samples.) For example, REL 768 is the mixed-population sample for A+1 at generation 500.
