Promoter characteristics in duplicates that were lost or retained following segmental duplication in primates. A The number of TF binding events in promoters of mouse genes, in sets of genes that recently duplicated in primates and were either lost or retained (380 and 120 genes, respectively). Comparison between the distributions was preformed using a Mann–Whitney one-sided test. B The fraction of lost duplicates, out of the total number of duplicated genes that have either a CGI or CGI-less promoter architecture, in sets of genes that recently duplicated in primates (enrichment was tested using Fisher’s exact test)
