After studying the chromosomes of the corn plant, Barbara learned of translocations, inversions, deletions and ring chromosome in the corn. This led to the deciphering of transposition in corn in Cold Spring Harbor, This is such a significant discovery because transposition proved the exchange of genes between the chromosomes.This was the first genetic instability to be found.
