Hey Leather, not to undercut your questions, but while you are waiting for a response...
I revived this thread the other day because someone thought that their jalapenos were so hot that they had been crossed with a habanero, even though they still looked as smooth and fleshy as any jalapeno out there.
I brought this thread back to show them the wrinkles this cross left on the pod.
I know that it is theoretically possible for a hab to be so far back in the family tree that there is no visible sign of it, but such diligence and patience to produce such a plant would probably result in expensive seeds or plants that would surely be marked as such. Wouldn't you say?
