How to know what makes a certain morph

I have found a few websites where I can input the parents and see what the possible outcomes would be. I was wondering if there were any websites where I could do the opposite. A place where I could put in a morph and see all the different combinations on how to produce that specific morph. Thanks in advance

On World of Ball Pythons (the same site with the Genetic Wizard) if you search for a specific morph it'll say in the description what morphs are used to make it

I've been keeping and breeding balls for a while and I still go to World of Bp to check what's in certain combos. It's a ridiculously useful resource.

I do not know of any web site that will do what the OP wants. I can do it by hand for many morphs, and I can tell someone how to do it, if anyone wants me to. (If so, send a PM because I'm not likely to hit this thread again.) It should be possible to make such a computer program, even. But there may not be enough interest for someone to do so.

World of Ball Pythons has a "morph list" that you can click the combo and it will bring up the page with the morphs needed to one side.

How to determine possible parents for a given morph

Limitation: This file is limited to situations when there are two possible genes (a mutant and a normal gene) for each gene pair. This makes nine possible matings per gene pair. If there are two possible mutants and a normal gene, then the possible mating list grows to 36, which is too unwieldy for this document.

The nine possible matings, male x female
1. AA x AA --> 1/1 AA
2. AA x Aa --> 1/2 AA, 1/2 Aa
3. AA x aa --> 1/1 Aa
4. Aa x AA --> 1/2 AA, 1/2 Aa
5. Aa x Aa --> 1/4 AA, 2/4 Aa, 1/4 aa
6. Aa x aa --> 1/2 Aa, 1/2 aa
7. aa x AA --> 1/1 Aa
8. aa x Aa --> 1/2 Aa, 1/2 aa
9. aa x aa --> 1/1 aa

1. Determine the target morph's gene pairs.
2. Using the nine possible matings list, determine all possible parents' gene pairs for gene pair #1.
3. Repeat step 2 with gene pair #2, gene pair #3, etc.
4. Make a list of the possibilities.

Example
1. Determine the target morph's gene pairs.
Desired morph is pied, spider, super pastel.
Gene pair #1 = 2 pied genes (pied gene is recessive to normal gene)
Gene pair #2 = a spider and a normal gene (spider gene is codominant to normal gene)
Gene pair #3 = 2 pastel genes (pastel gene is codominant to normal gene)

2. Determine all possible parents' gene pairs for gene pair #1.
A gene pair made up of two pied genes is symbolized aa. Matings 5, 6, 8, and 9 have aa among the offspring.

3. Repeat step 2 with gene pair #2, gene pair #3, etc.
A gene pair made up of a spider gene and a normal gene is symbolized Aa. All matings except 1 and 9 have Aa among the offspring. As no one has demonstrated a ball python with two spider genes (AA) in the gene pair, all matings with an AA parent can be deleted. That leaves matings 5, 6, and 8.
A gene pair made up of two pastel genes is symbolized AA. Matings 1, 2, 4, and 5 have AA among the offspring.

4. Make a list of the possibilities.
For pied:
het pied male x het pied female
het pied male x pied female
pied male x het pied female
pied male x pied female

For spider:
spider male x spider female
spider male x normal female
normal male x spider female

For super pastel:
super pastel male x super pastel female
super pastel male x pastel female
pastel male x super pastel female
pastel male x pastel female

Any male in the pied, spider, and super pastel listings can be mated to the corresponding female(s) to produce the desired morph. Or any female in the pied, spider, and super pastel listings can be mated to the corresponding male(s) to produce the desired morph. For example, a pastel het pied male ball python could be mated to either a pied spider super pastel female or a pied spider pastel female or a spider super pastel het pied female or a spider pastel het pied female.

Clear as mud?

It can be done just in a different way than how the combos come out when you pair a Male x Female. It can be rather labor intensive too.
Basically you would just search the "morph list" for the genes you wish to see preferable in a already known combo like a Bumblebee for example. That will give you a Pastel & Spider combo. Than the list will include all up to date possible combinations. It can be rather a long list depending on how established the morphs are.

Now remember World of Ball Python is not exact. With the degree of variation within each genes make up some combos can be slightly or drastically different looking, and there are also a few errors with some of the combos on how they are labeled. Its a great resource, but nothing like 1st hand knowledge.
