Association, linkage, and joint tests of association and linkage. Negative log10 of the median p-values are presented for analyses of the first 10 replicate simulations from the GAW14 data. Main effects of association, linkage, and joint linkage and association are shown for six chromosomal regions, four related to the KPD phenotype, D1–D4, and two regions, R1 and R2, that are in LD but are not related to KPD.
