Figure 1. Heat maps and hierarchical clustering of gene expression for females, subordinate males and dominant males.

Shown is the relative expression for autosomal male-biased (n = 2,217, panel A), female-biased (n = 2,908, panel B) and Z-linked (n = 364, panel C) genes. Hierarchical gene clustering is based on Euclidean distance for average log₂ expression for each gene for the three sexual morphs. The number at each node is the percentage bootstrap result from 1000 replicates.
