In any case only one layer is changed and hence gives rise to a chimaera with, mixed tissues: a layer of mutant lies inside or outside a layer of the unchanged type. Chimaeras can be produced artificially as graft-hybrids or by any treatment which alters the chromosomes.

When they are propagated from root-cuttings (or from disbudded tubers) shoots grow out of the concealed irmer layers which reveal the chimerical structure and the ancient mutations of these plants. The elucidation of these properties by Baur, Bateson, Winkler and Crane has enabled us to understand that natural changes in the arrangement of tissues lead to the repeated appearance of "sports" III.
