Yes. Generation skipping. A process where genes are passed along
but turned off in the initial cross, then reactivate in the following
generation. Unfortunately that would probably work two ways and
easily could cause the results I've experienced. Simply put, it is
true that a stronger growing plant is more likely to be able to
produce seeds. It's certainly true that plant strength has shown
back up in a subsequent generation but, statistically, I think the
numbers of plants involved too few to draw any good conclusions.
