Help with a genetics puzzle

[Mudturtle013]

Hi everyone, I am new to the forums here, but recently, my ball pythons have started to near breeding ages, and some may be ready as early as next year if they keep on feed.

I now have to switch from "awesome pet" mode to "breeding/genetics/probability" mode.

Here is my collection thus far.


Males:

Spider
Pastel


Females:

Orange Ghost
Pinstripe
Spider
Pastel


Possible Combinations:

Spider X Pinstripe – Spinner
Spider X Orange Ghost – Honeybee
Pastel X Pinstripe – Lemon Blast
Pastel X Orange Ghost – Pastel Hypo
Pastel X Spider - Bumblebee
Pastel X Pastel – Super Pastel
50% Pastel
25% Super Pastel
25% Normal



Now I've obviously come up with some ideas, but I need major help here on figuring out exact probabilities on these guys.

I'm having trouble filling in the gaps. Any help would be hugely appreciated.

Thanks so much, and I'm excited to talk about BP's.

You will probably find it easier once you realize that the only thing that matters is whether a snake is homozygous or heterozygous. Well, after that, there is combos, but you don't have any of those yet so it is easy.

You have mostly heterozygous snakes: the pastels for sure, and we can assume the spiders and the pinstripe also.

You also have one homozygous snake, the hypo (orange ghost).

In pairing 2 heterozygous snakes, you'll get 4 different possible outcomes, in equal ratios. The offspring will either have both genes, only the first gene, only the second gene, or neither. If you pair 2 pastels, the "one or the other" possibilities end up being the same, so that is why you get 50% pastel, which is the same as 25% pastel plus another 25% pastel.

In pairing a heterozygous snake with a homozygous snake, you have only 2 possible outcomes. All snakes will have 1 gene from the homozygous snake, and half of them will have the gene from the heterozygous snake and half of them won't. If, for example, you pair your hypo with the pastel, you'll get 50% pastels het hypo, and 50% het hypos.

Please understand this is a very quick and simple explanation. I'm in a bit of a hurry! If it makes no sense to you, ask and I'll try to explain in more detail later.
