Fig. 2From: A common regulatory haplotype doubles lactoferrin concentration in milkFine mapping of the locus surrounding the LTF gene for Lf protein and co-located molecular QTL. a–d Show the sequence-resolution Manhattan plots of the QTL peaks for (a) the log-Peak Lf protein QTL; (b) the LTF eQTL; (c) the ATAC-seq caQTL for peak 93 (BTA22:52946445–52948019); and (d) the ChIP-seq hQTL for H3K4Me1 peak 196 (BTA22:52960026–52962680). All four are coloured by the absolute values of the association \(\beta\)-values. Variants highlighted in green are those which have absolute \(\beta\)-values in the top 5% for all four phenotypes. The positions of the LTF gene and the two chromatin peaks are indicated at the base of the figureBack to article page
