Crabs Have Claws on Their Front Legs and Many Sets

Essay

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 transplanted onto the stump. If homeobox genes are responsible for the differentiation of leg types, what would you predict would happen to the stump? Describe analogous experiments that have been performed in other species.
