In Drosophila, the hunchback gene encodes a protein (HB) that is required in the correct concentrations for proper segmentation of the embryo. In the zygote and embryo, the expression of hunchback is stimulated by high concentrations of Bicoid protein. You manipulate a Drosophila embryo to have high Bicoid concentrations throughout. Which of the following would occur?
A. The HB protein would not be produced at all. B. The HB protein would be produced throughout the entire embryo. C. Segmentation would not occur correctly. D. The HB protein would not be produced at all and segmentation would not occur correctly. E. The HB protein would be produced throughout the entire embryo and segmentation would not occur correctly.
