Fig. 1. Chromosome-7(5H) test-statistic scan from simple interval mapping in the barley population Steptoe/Morex based on means of -amylase activity across none environments. The chromosome is oriented with the "plus" arm on the left. A horizontal scale shows centimorgan positions (tick mark every 25 cM). Horizontal solid lines show significance thresholds estimated from 1000 permutations of the data to maintain the per-genome Type I error rate below 0.05.
