And then this brings us back to the original question. Any variation
is just that and may or may not be reproduced in seedlings depending
upon whether the variation becomes 'fixed'. Generally, you can bank
on variations being 'one-offs' and unlikely to be reproduced amongst
the majority of seedlings. If you want to be certain of being able to
reproduce a variation, the only reasonably certain method is to
propagate vegetatively. That is assuming the variation is stable and
not prone to reversion.
