Gene expression in liver, brain and heart (three symbols for each line) for the three different populations (three lines per gene). Each letter represents a gene, expression values are log2 transformed and are indicated for liver, brain and heart (left to right) in each of Maine (circles), New Jersey (triangles) and Georgia (squares) populations. (a) Genes consistently different among tissues in all three populations are grouped as those involved in oxidative phosphorylation (upper panel) and those involved in other metabolic pathways (lower panel). (b) A representative subset of genes not consistently different among tissues in all populations. Gene names associated with letters are provided in Table 1 and Additional data file 1.
