Why do Drosophila wings develop in only one particular thoracic segment, legs in all three, and antennae on the head? Which of the following answer is correct?

#Unit 5. Developmental Biology
  1. The types of appendages produced by each segment reflect the identity conferred on that segment by the pattern of Hox gene expression along the antero-posterior axis in the embryo.
  2. The types of appendages produced by each segment reflect the identity conferred on that segment by the pattern of segment polarity gene expression along the antero-posterior axis in the embryo.
  3. The types of appendages produced by each segment reflect the identity conferred on that segment by the pattern of gap gene expression along the dorso-ventral axis in the embryo.
  4. The types of appendages produced by each segment reflect the identity conferred on that segment by the pattern of pair-rule gene expression along the dorso-ventral axis in the embryo.
