#Unit 5. Developmental Biology
  1. every other segment would be missing, resulting in T1, T3, A2, A4, etc. but no T2, A1, A3, and so on.
  2. segments A2 through A6 would be missing, but the rest of the pattern is essentially normal
  3. patterning within each segment would be abnormal, causing for example denticle belts to form across the entire segment
  4. the identity of one or more segments would be transformed to that of a different segment, such that the T3 leg would transformed to a T2 leg
