Die Gefahr einer Fälschung durch fremden Pollen ist jedoch bei Pisum eine sehr geringe und vermag keineswegs das Resultat im grossen Ganzen zu stören.
The danger of adulteration due to foreign pollen is however very slight in Pisum and on the whole in no way able to disturb the result.
adulteration = Fälschung See p. 5, s. 6.
foreign = fremden See p. 5, s. 6.
on the whole = im grossen Ganzen Both Bateson and Sherwood read this as an adjective, and translate “general result” and “overall result” respectively. The expression is adverbial, however, and implies an abstraction from occasional exceptions.
