General analysis of H3K27ac ChIP-Seq data revealed that the active chromatin was divergent between left and right gonads in both sexes. A PCA of the ChIP-Seq datasets from the four types of gonads. FL: female left, FR: female right, ML: male left, MR: male right. B Venn diagrams indicating the number of H3K27ac peaks for each sample and the overlapped peaks between the left and right gonads in females. The percentage of left- and right-specific peaks among all the peaks in left and right female gonads were shown in brackets. C Venn diagrams indicating the number of H3K27ac peaks for each sample and the overlapped peaks between the left and right gonads in males. The percentage of left- and right-specific peaks among all the peaks in left and right male gonads were shown in brackets. Note the dramatic difference of H3K27ac peaks between left and right gonads were found in both females and males
