Is shininess dominant?

[MintyMyndi]

I recently bred a Chao that was (more than likely) homozygous for shininess with a pure normal Chao. I bred them 14 times, and each result was shiny.
Offspring of the two Chao, in order:

Spoiler:

Shiny Silver Yellow
Shiny Silver Purple
Shiny Monotone Yellow
Shiny Silver Purple
Shiny Monotone Purple
Shiny Monotone Yellow
Shiny Monotone Purple
Shiny Silver Yellow
Shiny Silver Purple
Shiny Two-Tone Yellow
Shiny Monotone Yellow
Shiny Two-Tone Purple
Shiny Silver Purple
Shiny Two-Tone Purple

This seems to suggest that, despite the site saying that they function the same way as other traits, shininess is dominant over not being shiny. Is this just a coincidence?

Also, every Chao descended from Milky, the first Chao that I've noticed this trait in, has had a high intelligence grade. If you count Milky, I've had four Chao that inherited this grade, and one born with it by chance that was not related. The unrelated one is a parent to the youngest "genius." Do the hidden grades function differently from the visible ones? Or am I just super lucky? The youngest Chao should be ready to mate soon, so I will see if "Dash" (the planned name for the resulting child) is also gifted with brains. If research needs to be done on this half, then... consider that my contribution, as I do not have access to a hacking device. I can only tell if they're smart when I level them, then race them.

I remember there being debate between two users a while back over whether or not shininess was dominant or not. I guess the main site settled on not, but your results would imply further testing is needed, and possibly modification to the main site. I will ask Mooncow about that soon, so thank you for pointing that out.

When it comes to Intelligence and Luck grades, I would have guessed they are like other grades, but that should also be tested eventually. I would just assume you were lucky, but I could very well be wrong on that. And unfortunately, I can not test out the hidden grade genetics myself, due to lack of hacking materials for the game.

I'll just say something to possibly help this further...
I play the GCN versions btw
In my games, I have a immeasurable bunch of shiny chao thanks to my pure Shiny Mono White, Glitter. I bred her with my other monos and I swear the only thing that would come out of the eggs would be Shiny Whites or the Shiny of the colour of the Monotone. I don't remember any normal Monos or such, and this was with every monotone colour.

As for the Intel/Luck thing, I have no clue, and I'm just going to assume like Mamkute that you were lucky.

Hmmm, yes. More research. Heh. Well, as for the hidden grades, it seems like it would make sense for the child to always inherit the higher grade. Since it's hidden, you can't check it without leveling/racing, and it would make things a lot easier if that were the case.
But, there's no way to know for sure.

I'm gonna bump this to show some things that may assist the answer. The mating of a heterozygous shiny Chao and a Chao who did not carry shininess resulted in approximately 50/50 results, which would point to dominance. I was taking note the whole time, and although I'd love to post the results, they're a lengthy (possibly 100+ children), abbreviated mess, and you probably wouldn't have time to read them. I might post once I clean them up a bit.
And the child I kept is not smart. That's nothing that a little inbreeding won't take care of. Heck, she probably carries smart herself. But, assuming it works the same as the visible grades, the recessive is less likely to show up. If I use my "pure" normal genius, that would be... a 2/3 chance? Then I could try to get all those A and S grades onto the child... I seriously hope she carries purple or monotone. I could use an MTN or nonshiny purple two-tone.
