From: An eQTL in the cystathionine beta synthase gene is linked to osteoporosis in laying hens

Manhattan plot of the significance (−logP) of the difference in expression of genes in the tibia between hens segregating for markers defining good (n = 8) and poor (n = 8) bone strength. x-axis: chicken chromosomes and distance along the chromosomes. The genes marked in red are those considered significant, the majority are in the region of the mapped QTL on chromosome 1
