Fraction of predicted sites covered in samples from a F
admixture population. Reads from each F2 sample were aligned to predicted sites, then predicted sites were placed in 2 bp bins, with the fraction covered in each bin indicated by the heatmap. A) The RsaI dataset, aligned against total predicted sites. B) RsaI dataset, aligned against the subset of predicted sites with sequencing coverage in the original RsaI B73 GBS experiment. C) HincII dataset, aligned against total predicted sites. D) HincII dataset, aligned against predicted sites with at least one read coverage in the original HincII experiment. Sample order is given, left to right, in Additional file 5: Table S1.
