The genetic composition of mouse resources for studying complex traits. The genetic makeup of a typical mouse strain is shown for the Collaborative Cross (A), Chromosome Substitution Strains (B), Outbred Stocks (C), and the Hybrid Mouse Diversity Panel (D). Two sets of chromosomes are shown for the Hybrid Mouse Diversity Panel because it is comprised of both inbred and recombinant inbred strains. Each rectangle represents a chromosome, and each color represents the genetic contribution from a different mouse strain. Mitochondria are not shown.
