For each group of social genes, we generated a set of 10,000 random groups of size N (where N is the number of genes in that particular group) sampled from a set that contains that group of social genes and its corresponding background set of genes. Two-tailed p values are defined as the probability of obtaining a mean as extreme as the observed only owing to chance after FDR correction for multiple tests
