From: Finding genes that influence quantitative traits with tree-based clustering
Genotype trees underlying two disease positions. Binary multilocus genotype trees underlying genes affecting phenotype Q1 from data set 1. ARNT is not significantly associated with Q1 using QTLTree, whereas KDR is associated. Numbers in boxes are values of the z statistic at the node; counts of individuals at the leaf are to the right. Counts for internal nodes can be calculated by looking at descendants. Colored boxes indicate evidence for association with phenotype within the tree: red, z > 2.0; pink, 1 ≤ z ≤ 2; and green, −2 ≤ z ≤ −1. Uncoloured boxes show no evidence of association with phenotype.
