Manhattan plot. Grand linear view applied to a Manhattan plot as part ofa genome-wide association study in Angus cattle. The y axis shows geneticvariance, calculated by sliding windows of five consecutive SNPs for theinfectious bovine keratoconjunctivitis (IBK; a type of pinkeye) score. The xaxis is the genomic coordinates with all the chromosomes side-by-side. Thehorizontal striping of color helps to indicate the end of one chromosome andbeginning of another. The plot is faceted by three different analysis methods.There is one extreme variance in the middle facet, in the region of chromosome23. There are also a few large values in other regions. According to theresults from the paper, three of these regions, 2, 13, and 23 are found to bepotentially indicative of a quantitative trait locus associated with IBK.
