Genome scans for days with significant QTLs. Three QTL associated with survival time were detected, on days 2 and 8 after infection with Kp. Experiment-wide thresholds of significance at 50%, 90% and 95% levels are logP = 7.8, 9.7 and 10.3, respectively (e.g. the p% threshold means that in p% of permutations the genome wide maximum logP across all analyses at different time points did not exceed the threshold). A. Scan at day 2 post infection showing QTL Kprl1 on chromosome 4 at day 2 of infection. B. Scan at day 8 post infection showing QTLs, Kprl2 and Kprl3 on chromosomes 8 and 18.
