This constitutes adaptation of the Idioplasm.

If the whole remaining line of Idioplasmic determinants in an ontogeny has reached development, the development of the germ-forming determinants finally follows as well from the configuration of the Idioplasm as from the nature of the organism.

External stimuli exerted on the organism are reproduced in the Idioplasm.
