I heard that Super Pastel x Super Pastel does not guarantee all offspring being Super Pastels. Is this true?

That is not true.

If you breed a super pastel x super pastel... you will get all super pastels.

There are no normal copies of the pastel gene between either super pastel parent (both are homozygous pastel). All the offspring from homozygous pastel X homozygous pastel will be homozygous pastel. This is because there are no normal copies of the pastel gene for them to get, only four copies of the pastel gene in the parent pair.

Perhaps whoever was talking to Chris was thinking of pastel (het) X pastel where each baby only has a 1/4 chance of being a homozygous/super pastel and a 1/2 chance of being a het/regular pastel and a 1/4 chance of being completely normal (i.e. not all pastels or better).

Ah! Someone [you know who you are] is a fibber!

Like Randy says, breeding a homozygous pastel to a homozygous pastel could only produce more homozygous pastels. However there is another possibility that could give the results you are talking about. It's possible that someone could produce a drop dead gorgeous heterozygous pastel that looks like a super but was in fact just a regular pastel, after all they can be quite variable. If you ever were to breed two super pastels together and ended up producing any normal looking offspring in the clutch, you could be sure that at least one of the parents was not actually a Super Pastel no matter what it looked like.

Oops. Actually a breeding between a super and a regular would produce all pastels with half being super pastels and half being regular pastels. If you produced any normal looking snakes, both parents would have to be regular (non-super) pastels.

...my friend's a FIBBER!

"Fibber" might be a little harsh.

It's easy to get confused. I find it helps to remember the genotypes (pastel = het, super pastel = homozygous) so you can use the same rules you have learned from recessive morphs. Albino X Albino = all albino so the same with super pastel X super pastel.

I've also wondered if it's always possible to tell super pastels from regular pastels short of breeding. Anyone heard yet of a supposed super pastel proving out not super or a supposed regular pastel from pastel X pastel proving out super? Hopefully it's pretty cut and dry to tell the difference.

No. Trust me. He's a FIBBER!!! Nice guy, though. That guy's cool.
