Based on the photographs in Figure 25.13, in which segments would the Antp gene normally be expressed
FIGURE 25.13 The Antennapedia mutation in Drosophila.
Genes Traits (a) A normal fly with antennae. (b) This mutant fly has a gain-of-function mutation in which the Antp gene is expressed in the embryonic segment that normally gives rise to antennae. The expression of Antp causes this region to have legs rather than antennae.
