Crabs have claws on their front legs and many sets of walking legs (which lack claws) on segments posterior to the claws.
 
  Crabs can regenerate legs if they are lost. A walking leg was removed and tissue from the claw was trans-planted onto the stump. If homeobox genes are responsible for the differentiation of leg types, what would you predict would happen to the regrown claw? What might be an analogous experiment from this chapter?
 
  What will be an ideal response?

ANS:
The walking leg was transformed into a claw because of signals from the claw tissue. This is analogous both to what happened with the neural crest transplantation experiment and the homeotic transformation experi-ments.
