FIG. 1.

Approximate boundaries of introgressed regions for each Bbaa QTL. Bbaa QTL were identified on Chr 1, 4, 5, 11, and 12. QTL were introduced into reciprocal backgrounds by backcrossing, with the introgressed regions from B6 mice indicated by solid lines and those from C3H mice indicated by dashed lines. Introgressed-region boundaries were determined by microsatellite marker analysis as described in Materials and Methods. The cytomaps used to generate this figure were retrieved from the Mouse Genome Database (Mouse Genome Informatics, The Jackson Laboratory, Bar Harbor, ME; http://www.informatics.jax.org) (6) in February 2009. cen, centromere; tel, telomere.
