But only such changes are transmissible to future generations as have resulted from modifications arising in the idioplasm.
Hence along with growing and complete determinants the idioplasm always contains likewise weakened and vanishing determinants.
Races arise from gamogenic or pathological variations of the idioplasm.
The others are inherited and again transmitted; they belong to the physiology of the idioplasm.
It will be found that characters totally contradictory are ascribed to Weismann's idioplasm.
