Blizzard x Normal

What would you get if you crossed a blizzard with a high yellow? It says on the morph calculator 100% normal het blizzard, but aren't there a lot more possibilities than that? Even if the parents don't have hets? Because weren't blizzards created eventually after selectively breeding normal leos until they were bred out to have no spots? So if you bred a high yellow with a blizzard, wouldn't it be at all possible to get hypos or even patternlesses?
Sorry for all the questions. This is confusing me a bit.

Thanks in advance. :)

EDIT: *In the title, I meant to put "Blizzard x High Yellow", but I guess it doesn't matter that much, since high yellow is just a polygenic trait.

Blizzards seem to some extent to be dominant/recessive rather than line bred. However if you cross a blizzard with a normal, they usually have lots of little speckly spots. Here's a picture of 2 of my normal/blizzard crosses taken in Nov. They've gotten a lot spottier since:

The high yellow I have has TONS of spots. More than I have ever seen on any other gecko. She was also in a batch with an albino, so I don't know if she's het for anything. The blizzard I have was with a ton of other blizzards when I got him. It's my first time breeding, and I do have others (blizzard x tremper snow, blizzard x SHTCT), but I was confused as to why only high yellows het for blizzard would come out of that crossing.

Would it be 100% high yellow 100% het for blizzard?

Thanks again!

High yellow is a line bred trait. "High yellow" really means that the gecko has lots of yellow and less black. Since it's line bred, if you bred it to anything else, the offspring are likely to have a range of spotting from not much to a lot. Since blizzard is largely recessive/dominant, you wouldn't get any blizzards unless your high yellow is somehow het for blizzard, but you would get speckles. The only way you'd get anything else besides speckled high yellows het for blizzard is if both of your geckos are het for the same "something else" (if they're both het for albino, for example, you'd get some albino offspring).
I hope that clarifies it.

the morph calculator is correct. from your pairing youd get normals or high yellow het for blizzard.

normal x recessive = normal het recessive.

recessiveXnormal ALWAYS is just normal 100% het for recessive trait.

Blizzard is a simple recessive trait. The only way to find out if a gecko is het for blizzard is to breed it to a blizzard and see what happens.

Thank you everyone! This clears up everything soo much! That seemed to be the only thing blocking me from getting those parts of the genetics. It makes a whole lot more sense now! :)
