            Column I

             Column II

A. when an early wing bud progress zone was transplanted to a late wing bud

I. Normal limbs form

B. when a late wing-bud progress zone was transplanted to an early wing bud

II. Lack of intermediate structures

C. when an early wing bud progress zone was transplanted to an early wing bud
