The question comes up as to why the information content for the two $\gamma = 16$ proteins of Fig. 1 do not give rise to a ratio of 2. The reason is that cI and cro bind to the same location in competition, so they share information. Presumably the two proteins that bind at T7 promoters do so simultaneously and do not use the same molecular contacts.
