Gärtner erwähnt, dass in jenen Fällen, wo die Entwicklung eine regelmässige war, unter den Nachkommen der Hybriden nicht die beiden Stammarten selbst erhalten wurden, sondern nur einzelne ihnen näher verwandte Individuen.
Gärtner mentions that, in those cases where development was regular, the two parent-species were not themselves obtained among the progeny of the hybrids, but only some individuals that were more closely related to them.
Gärtner Mendel may be referring to a section on “Blended types” (Gemengte Typen) in Gärtner’s book, which the latter defined as hybrids in which “partly this, partly that part of the hybrid comes closer to maternal or paternal form; where the characters of the parents, however, never are transmitted purely to the new organism” (Carl Friedrich Gärtner, Versuche und Beobachtungen über die Bastarderzeugung im Pflanzenreich, Stuttgart: Hering, 1849, p. 282). From Gärtner’s discussion it becomes clear that “regular development” of hybrids occurs when the “typical” or “formative forces” of parental plants are in balance so that the hybrids “tend” toward the paternal and maternal form in equal degrees (op. cit., p. 279). On Gärtner, see p. 3, s. 4.
more closely related = näher verwandt See p. 39, s. 7.
parent-species = Stammarten Bateson has “original species”, Sherwood “parental types”; see p. 5, s. 10.
