Genome-wide scan for dental fluorosis phenotypes for mouse Chromosomes 1−19 (excluding X and Y chromosomes). The p values obtained from Chi square analyses were converted to -log of p values and plotted on the y axis vs. the relative location along each chromosome on the x axis. Data are from 107 mice representing the phenotypic extremes of animals scored as either a clinical dental fluorosis of 1 or a 4 from a panel of 458 F2 mice.
