Viktor Hamburger found that removing the limb bud from one side of a chick embryo resulted in fewer motor neurons on that side of the spinal cord at hatching. What are two possible mechanisms by which limb bud removal could decrease the motor neuron pool? What follow-up experiment was designed to clarify this result, and what did it find? What are two possible mechanisms that could explain the result of this follow-up experiment?
