Power of the test developed by Jiang and Zeng (1995) to differentiate close linkage from pleiotropy in linkage-simulated scenarios considering different levels of minor allele frequency (MAF), balanced percentage of explained genetic variation (QTL size) for each of the two simulated traits, linkage disequilibrium (r2), and marker profiles of the 358 European winter plus 15 spring wheat varieties (GABI-WHEAT population). Each value corresponds to the proportion of times in which H0: p(1)=p(2) was rejected in 100 simulated replicates
