Complex trait association and/or admixture mapping was a focus for three contributors, and both real and simulated phenotype data were analyzed. Chen et al [2013] and Yorgov et al [2013] analyzed real SBP and DBP phenotype data. Yorgov et al. additionally analyzed a simulated Q1 phenotype that was not influenced by genetic factors. Thornton et al. [2013] analyzed a simulated DBP phenotype.
