Chromosomal locations of the quantitative trait loci (QTL) for collagen-induced arthritis incidence on chromosomes 1 and 11. QTL for collagen type II (CII) antibody titers are illustrated on chromosome 13. *Suggestive level threshold (P = 0.63) according to the permutation test (n = 1,000). ** Significance level threshold (P = 0.05) according to the permutation test (n = 1,000).
