Blastogenic Variation
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Blastogenic variation is an obsolete term introduced by Ludwig Plate to designate variations arising from changes in germ cells, as opposed to somatogenic variations. Because Plate included both mutations and fluctuations among blastogenic variations and considered not all of them heritable, the term fell out of use as inaccurate.

BLASTOGENIC VARIATION, an obsolete term introduced by Plate to designate variations arising as a result of changes in germ cells, in contrast to somatogenic variations arising as a result of changes in body cells. But since Plate did not consider all blastogenic variations to be heritable and referred both mutations and fluctuations to them, this term, being inaccurate, has fallen out of use.
