Fig. 2From: DNA and RNA-sequence based GWAS highlights membrane-transport genes as key modulators of milk lactose contentManhattan plot showing QTL locations for lactose yield. The X-axis shows the positions of 1.1 million variants across the 29 autosomes in the UMD 3.1 Bos taurus reference genome; the Y-axis shows the negative log of the p-values calculated for each variant for a lactose yield QTL. Variants illustrated using a triangle sit beyond the limit of the Y-axis. The black and red lines as per Fig. 1 legendBack to article page
