Need a hand, new to genetics with surprise gene babies.

This is Oreo(black and white) and snowy (white and pale pink) their parents are a blizzard eclipse het bell (dad) and a bell her blizzard eclipse. Snowy has a snake eye and a pure eclipse eye, an I cannot put my finger on what her morph is. Oreo my guess is macksnow. How did a macksnow pop up though? I know dads parents produced a few macksnow babies (I own his brother, a bell macksnow) but how did it come that far down the line? It baffles me as I'm already trying my hardest to learn morphs and these beauties pop ou of a line I thought I had figured out! Thank you on advance.
I also have another question
, I bred a reverse g stripe het Tremper to an emerine het Tremper and got a normal baby. What to I put as the hets other then tremper?

Snow is a dominant gene. In order for a baby to be snow one of the parents must be a snow. Your first baby looks like a normal mack snow. The second (could just be lighting) looks a bit paler like an albino mack snow. Do you have pics of the parents? Sometimes with the "white" geckos like ones that have Blizzard and MP in their background it is very difficult to tell if they are snow or not cause you're looking for white on white. It takes a very experienced eye to spot it but sometimes it hard to tell for everyone.

If you breed two hets together all babies that are not visually expressing the gene have a 2/3 chance of having the het so they should be labeled 66% het tremper (or whatever the gene is).

There's mom and dad, dad is a little darker then usual today he hasn't scootched onto the heat cable. This pair hasn't produced a single normal yet out of 4 eggs! Definitely a keeper pair for me

A few years ago I bought an aptor possibly het raptor as a breeder female. I paired her with my hypo Mack snow het eclipse. Imagine my surprise when the first hatchling was an eclipse supersnow! It turned out that the female, which I'd bought as an adult, was a Mack snow as well (the breeder I got her from had gotten her from someone else who hadn't included the Mack snow designation. (This season, I bred her to a Tremper Mack snow het eclipse and have produced 3 Tremper super snows, one of which is definitely eclipse as well).

It's pretty tough to tell when a baby blizzard has a snow gene since they're white or...well...whiter. I would guess your blizzard male has a snow gene too.
