In drosophila, Head formation required higher Bicoid concentrations than thorax formation, because

#Unit 5. Developmental Biology
  1. The promoters of such head specific genes would have high-affinity binding sites for Bicoid protein, causing them to be activated only at extremely high concentrations of Bicoid.
  2. The promoters of such head specific genes would have low-affinity binding sites for Bicoid protein, causing them to be activated only at extremely high concentrations of Bicoid.
  3. The promoters of such head specific genes would have high- affinity binding sites for bicoid protein, causing them to be activated only at extremely low concentratrations of bicoid.
  4. The promoters of such head specific genes would have low-affinity binding sites for Bicoid protein, causing them to be activated only at extremely low concentrations of Bicoid.
