eQTL plots for hypothalamus. eQTL plots were generated using three haplotype association mapping (HAM) methods: (A) parametric analysis, (B) nonparametric analysis, and (C) weighted nonparametric analysis. In all plots, the x-axis represents the genomic SNP axis and the y-axis represents the genomic probe set axis. Each spot represents an association between the expression of a gene and the strain distribution pattern at a SNP location. Alternating colors indicate chromosome boundaries on the x-axis. In each plot, the top 10,000 eQTL associations are shown.
