During anteroposterior patterning in Drosophila pair-rule genes are expressed in every other segment (i.e. in 7 stripes). In contrast, segment polarity genes, whose transcription is controlled by combinations of pair-rule genes, are expressed in every segment (i.e. 14 stripes). Suppose that you are studying the effects of a loss of function mutation in the pair-rule gene even-skipped (eve) on the segment polarity gene, hedgehog (hh). What would you expect to see if you stained an eve(lf) mutant embryo using an antibody able to detect the hedgehog protein? Explain.
