Orthologs are represented in pairs of columns by Sox group. Expression is indicated by a plus sign (+). A single asterisk (*) shows agreement in expression patterns between orthologous genes from the two ctenophore species. ‘nd’ denotes no data. The double asterisk (**) for MleSox1 expression in the comb row refers to light expression seen only in the uppermost part of the comb row at the cydippid stage.
