More beginner questions about back-crossing

[alecStewart1]

Hey guys, I have a question about back-crossing.


Take any of your favorite hybrids.

Say we have a plant that's the same hybrid or species as the parent, but has a notable different trait. We back-cross the hybrid with this other plant with a different trait than one of the original parents, and we get some progeny that may be different in some notable way.

Is this likely?

Then say we take this different progeny, and we cross it back with the other parent of the original hybrid.

Is this likely to produce something like the original hybrid, or a new varied one?

I'll give an example:

Rhynchonopsis Dragon Charmy (Phalaenopsis japonica x Rhynchostylis gigantea)

Rhynchonopsis Dragon Charmy x Rhynchostylis gigantea 'Cartoon' = maybe more clear spotting on flowers?

(Rhynchonopsis Dragon Charmy x Rhynchostylis gigantea 'Cartoon') x Phalaenopsis japonica 'Minmaru' = maybe smaller plant as well as better spotting of leaves?


Or, disregarding all of this, do we instead just attempt a hybrid/grex using the same parent species/hybrids, but with different traits to maybe produce a different variety of a given hybird/grex?

So

Rhynchostylis gigantea, orange flower (if that even exists) x Phalaenopsis japonica 'Minmaru' = slightly different flower and slight smaller plant?


I know genetics is a roulette wheel, and breeding can be like playing blackjack (you're at 15, and you could get a 6, but you could also get everything else) but there's gotta be way to sort of...make a pretty good guess on what you'll get.
