Large genomic deletions fixed independently during laboratory adaptation. Deletions covering genes 4.5–4.7 fixed during adaptation in response to a thermal challenge while the deletion covering genes 0.3 to the protein kinase fixed during adaptation to the Amberless host (a locus where adaptive deletions have been reported in previous studies) (Cunningham et al. 1997; Hammerling et al. 2014). Precisely replicated deletions in populations S2 and S3 are possibly attributable to contamination; however, the two populations share only four SNPs, while a further fourteen SNPs distinguish them.
