25% Pastel Spider
25% Spider

25% Normal
am I right?

I'm not sure about the percentages, but yes, those are the morphs you'd produce.

1.0 Pastel Ball
1.1 Het VPI Axanthic Balls
1.1 Het Albino Balls
0.0.2 Red Tail Boas
1.0 Albino Nelsoni Milksnake
1.1 Room mates
2.2 Dogs
0.1 Cat

i think spider,bumble bee, pastel, normal

I THINK that is the percentage for each egg and not always the whole clutch... am I right?

Actually I believe that is the percentage for the whole clutch. I'm just starting to learn about the genetics myself, so somebody please correct me if I'm wrong.

No, each egg has a 25% chance to be one of those combinations (bee, spider, pastel, normal). It is possible you could luck out and get all bees, or you could get all normals.

Really it doesn't matter which way you look at it. They pretty much mean the same odds. I believe if you go by the book it is for the whole clutch. One of the first things that I learned is that they are just a guideline. You could get unlucky and hatch out nothing but normals or very lucky and get nothing but Bumblebees (Spider/Pastel Mix). Every clutch is kind of a roll of the dice, but the percents that you had are correct.

The real difference is this: If you say it goes by the whole clutch, it implies that the results may be dependent upon what the other hatchlings are. Each egg has certain odds of being something which is completely independent of the other eggs. So if you've hatched every egg in a clutch and they're all bees, the last egg still has the exact same odds that the other ones did. It's not more likely or less likely to be a bumblebee as well.

Now, the odds of what will pop out will hold true for a large sample size. So, if hypothetically speaking, you bred the same pair ever year and ended up with 100 eggs in total, you should get around 25 normal, 25 pastels, 25 spiders and 25 bees. Ball pythons have such small clutches that you're much more likely to have clutches that vary wildly from the predicted odds.

Thats basicly what I was trying to get at, it really doesn't matter if ya base the odds on the eggs or clutch. Crazy things happen... I just didn't word it very well.
