I'd be moderately surprised if cross-pollination significantly changed
the phenotype of sweet pepper and chile fruits (rather than the fruits

As I said, I have not observed it, though my experience is not
immense. I have usually grown several types of chilli, though
all tend to be hot. In no case has the flavour or shape deviated
from what I would have expected.
