Transcription of the developmental gene m is influenced by two different proteins: b and h. studies of single and double mutants generated the following information: in mutants lacking b, transcription of m does occur in mutants lacking h, transcription of m does not occur. in double mutants lacking b and h, transcription of m does occur. based on this information, put these genes in order in a developmental pathway. use arrows and t-bars between the genes as appropriate. choose the correct identity of each box below.
