Fig. 6

Dendrogram of hierarchical clustering analysis using A. mellifera expression data. Hierarchical clustering analysis was performed using A. mellifera expression data as input. The dendrogram was drawn based on the result of the hierarchical clustering analysis. In the dendrogram, queen samples were colored yellow. In worker samples, larva, pre-pupa, pupa, and adult samples are colored light blue, blue, purple, pink, and red, respectively. The sample categories containing two stages are indicated in two colors (e.g., samples containing both larva or pre-pupa stage are colored in blue and purple). The manner of coloring is the same as that in Fig. 4. The biological replicate numbers of some sample categories do not begin with “1” and are not sequential (See “Methods” part.).
