But, just to give you the very basics of your question, here goes:

Prerequisite - each snake carries genes from its father AND genes from its mother.

1.) Dominant - a morph gene is dominant if you only need one parent to pass on the gene and there is no super form of the morph. So, pinstripe is dominant because you only need either the mother or the father to be pinstripe to get pinstripe babies AND if both mother and father are pinstripes you don't get a different morph - you get pinstripes, where a possibility exists that some of the pinstripe offsprings have double pinstripe genes (you won't be able to tell which pinstripe is just a single gene pinstripe, or a double-gene pinstripe just by looking at it because they would look exactly the same).

2.) Codominant - a morph gene is codominant if you only need one parent to pass on the gene and there is a super form of the morph. So, pastel is codominant because you only need either the mother or the father to be pastel to get pastel babies AND if both mother and father are pastels, you could possibly get a completely different morph - a super pastel.

Simple enough?

Okay, as far as offspring... saying "50% of the offspring should be pinstripes" is not quite the right idea. The 50% number is the statistical chance of getting that morph per egg.

So:

3.) Pinstripe to normal - because you only need one parent to be pinstripe, you'll get a chance of having pinstripe babies. Now, if that pinstripe's parents (grandparents of the eggs) are both pinstripes, then the pinstripe is double-gene - so every single egg produced in this pairing will be a pinstripe. But, if one of the grandparents is not a pinstripe, then each egg produced by this pairing will have a 50% chance of being a pinstripe.

4.) Pastel to normal - because you only need one parent to be pastel, you'll get a chance of having pastel babies. Every single egg in that pairing will have a 50% chance of being a pastel.

Bonus:

5.) Super Pastel to normal - that is, you got a double-gene pastel. All your eggs are guaranteed pastel.

Have fun!
This statement has me a little confused. I was unaware of any pins that through only pins (super/Homo), I may have missed them. That being said, even if both parents are pins and there is a homo form, only 50% of the pin babies should be Homo, unless i am missing something
