Principal component analysis of gene expression profiles. (a) Morphology of body (left) and flight feathers (right). (b) Principal Component Analysis (PCA) of gene expression profile. The results were obtained by analyzing 12,608 genes with FPKM >0.1 in all libraries. cEB, early body feather of chicken (pennaceous); cLB, late body feather (plumulaceous); cEF, early primary flight feather; cMF, middle primary flight feather; cLF, late primary flight feather (calamus)
