Let me explain. I first thought that PBF was dominant.This is that one of
the parents
had to express this modifer to pass it on.But from making a few test crosses
and 500 seedlings. I found it to be a ressive trait.This means that both of
the parents carry the modifer but do not express it.So we do not see it but
we know it's there.
So lets say that we cross a PBF with a non PBF and get none.We know that non
PBF parent doesn't carry this modifer.But we can also cross a non PBF to
another
non PBF and if we get PBF seedlings they both have to carry this modifer.Some
iris
don't express this modifer as well you really have to look close sometimes in
late fall
or early spring to see it.More test need to be done to beter understand
PBF.3/4 of my seedlings have PBF.
