I've been looking for a listing of Genetic Codes for all the Ball Python morphs.
Is there such a thing, and where can I find it?

Thank You,
Ken

Huh? I'm not sure what you mean by "Genetic Codes" especially when you are talking about ones that pertain to ball pythons exclusively.

Please explain what you mean and maybe we can help you a little more.

NN = Normal
aa = Albino
p* = Pastel (I think)
?? = Pinstripe
and so on.....

I'm trying to make up some Punnett Squares, and it would be nice to use the correct code for each animal.

Thanks for any and all help,
Ken

There is no standard "code" for what you describe. Its sort of up to whomever is doing a punnet square. Basically, pick a letter and go with it....you could do squares and circles for that matter. Also, the normal "code" is going to be a derivative of the mutation...in other words, when talking about a simple recessive mutation such as albinism, an albino would be aa, while the normal would be AA, and hets would be Aa.

As already said there is no code for different snakes there are just letters, numbers, or symbles which ever you prefur.

To help you out a basic tips.

First understand Domin and Codom. breading. Example, Pastel x normal, Pastel x Pastel, Pastel x Super, and Super x Super.

I am assuming you understand these already. Now where things start to get confussing is when you use simple ress. gene. For example the Clown. I found it easiest explaned like this. Look at a Clown (or any visable ress. morph) as a super, each babie will get 1 copy of the gene; however, for a ress to be visble both parents have to contibute that gene to the baby, where as in Domin/codom if one contibutes it is visable. So it is kind of like saying your Pastel is a het Super pastel.

When it comes to picking out your coding just make sure that you different morphs have a differnt symbol and keep practicing.

Genetics is one of those things that will make your head hurt for days and days and then one day i just clicks and becomes fun rather then frustating.

Also feel free to double check your work by posting what you think your results would be and we can let you know if you got it.

The post below about breeding a Bumblebee x Normal, and hatching Bumblebees.

This is what I did for Pastel x Spider:
I used Np for Pastel and Ns for Spider (I used the N for Normal).

     N s
N NN Ns
p Np ps

This gives me 25% Ns (Spider), 25% Np (Pastel), 25% NN (Normal), and 25% ps (Bumblebee).

Now this is what I did for Bumblebee x Normal:

     p s
N Np Ns
N Np Ns

This gives me 50% Np (Pastel) and 50% Ns (Spider)

What am I doing wrong?

Thank you,
Ken

The basic mistake you are making is that you are not representing both genes for the appropriate allel for each trait. You need to represent both parents respective genes. even though one of the parents are normal since we are looking at breeding it with a morph then the normal animal still needs to represent the given morph(s) that we are talking about. It is traditional to represent a morph with lower case letters and without trait as a capital letter for example a bumblebee needs to be written like PpSs. With the Pp representing that it carries one gene for the pastel morph and the Ss representing the same thing for the spider morph. The normal that it is still being bred to will also have to represent all the same genes but since it it not a carrier for any of them then it will be all capital letters, PPSS.when you are dealing with two seperate morphs your punnet square will double in size to 16 blocks and when labeling you need to represent all four possible combination of genes that they can provide to the offspring. The bumblebee should look something like this:

PS Ps pS ps
PS

PS

PS

PS

The normal has no choice but to give normal genes but the bumblebee has four different possible combinations. So this being said the whole punnet square should look something like this:

PS Ps pS ps
PS PPSS PPSs PpSS PpSs

PS PPSS PPSs PPSS PpSs

PS PPSS PPSs PpSS PpSs

PS PPSS PPSs PpSS PpSs.

Remembering that the capital letters represent without trait (normal) and the lower case represents with trait then we can determine that you have a 25% chance per egg of either normal, spiders, pastels or even bumblebee. I know this is long but i hope it breaks it down for you a little easier, Todd

the program that runs the test messed up the outline for my punnet square but if you just shift the letters apart a bit you should be able to understand it. Todd

OK, now I get it.. Thank you for your help!

There is no recognized set of symbols for ball pythons.

Ideally, each mutant has a unique name and a unique symbol based on the name. "A is for apple" is common in alphabet books. So, "a is for albino" can start your genetics symbols.

Recessive mutant symbols are lower case. Dominant and codominants have the first letter uppercase.

Examples of possible symbols for mutant genes:
a = albino (a recessive)
P = pastel (a codominant)
pi = piebald (a recessive)
Ps = pinstripe (a codominant, I think)

The plus character, either by itself of as a superscript, is the internationally recognized symbol for the wild type or normal gene at each location in the genome. Unfortunately, kingsnake.com filters out several seldom-used characters, including the plus.

a with plus for a superscript = the normal version of the albino mutant gene.
P with plus for a superscript = the normal version of the pastel mutant gene
pi with plus for a superscript = the normal version of the piebald mutant gene
Ps with plus for a superscript = the normal version of the pinstripe mutant gene

Hi.............To keep it simple AGTC repeated about a billion times and you have a ball python or its dinner!!!.......adenine, cytosine, guanine, thymine............Sorry could not resist the temptation.................God Bless, Lee Van Hyfte

Genetics... bloody confusing

but for each morph trait, no real convention on what lettering to use, other than capital letter for a dominant gene, smaller case for a recessive gene.

I have found the site above has pretty good detail on genetics, even if most of their samples are more for corn snakes than ball python morphs but the basic principals still apply.
