What experiment can be used to prove that the rudiment of one organ determines the development of other organs?

It is possible to prove that the primordium of one organ determines the development of others using an experiment in which a portion of the dorsal side of the body is taken from the embryo at the stage of the early gastrula, from which the chord and mesoderm should later develop, and transplanted onto the ventral side of the other gastrula. As a result of this transplantation, an additional neural tube was formed on the ventral side of the second gastrula from the cells, which were supposed to give rise to the skin integument. This phenomenon is called embryonic induction.
