Use the figure from Martin et al. 2016 below to answer the subsequent questions. с abd A Amphipoda anterior appendages Flogs Rlegs pleopods uropods abd-A Decapoda Ana A22 Ma 12 Mirp T4 T5 T6 T7TA1 A2 A3 A4 A5 A6 pleopods gonopod podoin anterior posterior legs legs Isopoda mbd-A AntA2MMM 2 T2 T3 T4 TST 17TSALAZAJ MASA6 pleopods uropod single leg type a. How do the abdominal appendages change between Amphipods, Decapods and Isopods? What is the role of abdA in facilitating this change? (5 pts.) b. The thoracic segments grow walking legs. What gene is responsible for growing legs in crustaceans? How do crustaceans change the amount of walking legs in each lineage? (4 pts.) c. The sister taxa to Crustaceans, Insects, only have three thoracic segments. The fewer thoracic segments weren’t caused by changing Hox gene expression, but segmentation genes. Explain the mechanism behind making the thorax smaller in Insects. (5 pts.) d. Insects also don’t use the same géne to specify their walking legs. What gene do they use instead? Use the comparison between Drosophila and Lepidopterans to explain how insects specify their legs differently from Crustaceans. (6 pts.)
