An intended cross is not always the obtained result, that is often
the problem with the parents of plants. People make a cross and
then assume the resulting seedlings are that cross Especially with
plants difficult to cross like plantaginea and many hybrids there is
always a fair chance that a stray pollen was around Especially if
you have only a few seeds one must be suspicious. In several
cases the parents indicated in the registration are the INTENDED
cross but the results clearly indicate that a stray pollen was around
Good examples are if two green/blue plants are crossed and the
result is a yellow offspring. ( yellow is a dominant character so
must be visible in one of the parents. ). Another is when a a good
species say hypoleuca is selfed and the resulting seedling is
different from hypoleuca.
