Die Hybride bildet so vielerlei Keimzellen, als die in ihr vereinigten Merkmale constante Combinationen zulassen, und eine davon ist immer gleichartig mit den befruchtenden Pollenzellen.
The hybrid forms as many kinds of germ cells as there are constant combinations that the traits united within it allow for, and one of these is always of the same kind as the fertilising pollen cells.
This sentence invokes the conclusion from Section 9 about the constitution of pollen and germ cells; see p. 32, s. 2. It is notable that here as well Mendel is not using the “laws found valid for Pisum” to explain Gärtner’s empirical observations.
as many kinds = so vielerlei On the suffix -lei see p. 42, s. 4 .
germ cells = Keimzellen See p. 24, s. 4.
constant = constante See p. 5, s. 5.
united = vereinigten Bateson has “conjoined”, Sherwood “associated”; see p. 41, s. 6.
of the same kind = gleichartig Sherwood has “just like”, we follow Bateson;ee p. 41, s. 7.
