I would disagree--something has been learned, namely that the crosses
didn't work.

But do the sib-type seedlings cross with the JI-type seedlings, and do you
get both phenotypes segregating from such crosses? In the original
crosses, from a single pod, are all the progeny of one type or another, or
are sib-types from siberian pod-parents and the JI types from JI
pod-parents?
