Fig. 6From: Dynamic transcriptome analysis reveals the gene network of gonadal development from the early history life stages in dwarf surfclam Mulinia lateralisDetermination of the timing of molecular sex differentiation. A Hierarchical clustering on all gonad samples based on the expression patterns of 80 sex differentiation-related genes from modules M11 and M14. B The PCA score plot of the first two principal components for the 40 gonad samples using the 80 sex differentiation-related genes. The ovaries, testes and undifferentiated gonads are shown with light pink, blue and yellow backgrounds, respectivelyBack to article page
