Inheritance of linking partners for duplication-based young genes (primate-specific genes). a The inheritance status for ‘real’ duplicate gene pairs in the context of PPI networks. b The inheritance status for random gene pairs in the context of PPI networks. The numbers inside the circles show the average PPI network connectivity for parental genes or children genes, and the percentages indicate the fractions of common linking partners shared by parental genes and children genes
