Actually, I'd be surprised if *any* geneticist said otherwise. By "vertical
transmission" I mean the context that the term is explicitly used in Wolff et
al. (2000), which is also how I understand the term:
"Galliforms acquire _T. gallinae_ through drinking
contaminated water [7,27], while falconiforms acquire it through
foraging on infected columbiform prey [21â26]. Vertical transmission
from parents to offspring has also been demonstrated
among falconiforms, either through nestlings being fed meat with
adherent flagellates in it or by direct bill-to-bill contact with
infected parents [21,22,23,26]."
So the parasite is transmitted by feeding, not by inheritance. Thus, it is not
"genetic". Similarly, if my mother gave me the flu because I shared her glass
of water it is not genetic either.
