Figure 1

ARI breeding schematic. This figure shows the breeding history, genetic derivations, and genotyping status of the BXD ARI strain set. We commonly refer to animals derived from the BXD AIL generated at Princeton University as "Group A" and animals derived from the BXD AIL generated at the University of Tennessee Health Science Center as "Group B." Group A animals are shown in gray. Genotyping refers to our dense, 588 marker effort. Nearly all strains in both groups are genotyped at 268 loci across the genome.
