Textbook Question
Textbook QuestionGiven that maternal Bicoid activates the expression of hunchback (see Figure 18.7), what would be the consequence of adding extra copies of the bicoid gene by transgenic means to a wild-type female with two copies, thus creating a female fly with three or four copies of the bicoid gene? How would hunchback expression be altered? What about the expression of other gap genes and pair-rule genes?
