Sonneborn, longtime professor of genetics at Indiana University, with researcher Beisson reported that if Paramecium cilia are surgically removed in clumps with their bases and turned around some 180 degrees on the cell’s surface, then replaced, the cilia will appear in offspring cells, for many future generations, in this reversed position.
