Ball Python DNA mapping

[BPSP]

I am in the process of developing a system for a ball python genetic library as well as DNA mapping for morph ball pythons. The process will result in a visualization of a selected ball python's genetic markers in order to validate genetics. This will primarily serve those purchasing high end snakes that are het for a desirable breed. An example would be, you are about to purchase a Spider het pied. You can visibly confirm the snake is a Spider. What about the fact that it is het for pied? Through database comparison a person will be able to guarantee a snakes genetics when the trait is not visually apparent. The process and output will be in the form of Gel Electrophoresis. This will allow for easy position matching for genetic similarity.

I want to get a more robust idea of the potential interest this service will have in the herpecultural world and any other information you may find useful. Any input would be greatly appreciated and help further develop the process, in turn enhancing the understanding of ball python genetic variability, and grow the overall understanding of ball python mutations.

It will have to be cheap, I would love to be able to test potential het purchases, but it simply would cost too much.

Good idea in theory, most likely not a good thing in reality. Genetic tests are expensive and timely. Its alot easier and cheaper to just buy from reputable breeders. I had my DNA mapped and it cost me nearly $500 for all the tests and took around 3 months to get the results. Definately a very interesting idea, I'm sure people would be interested in the knowledge about certain genes but not for testing hets.

I have done Gel Electrophoresis before. Very interesting process.

What lab are you going with? I was considering speaking to my university's genetics lab for headway on a similar project.

I will be performing all of the work and analysis myself. I am going to start by building a library of samples to compare to. Then move on to comparative work for individuals seeking genetic confirmation or variation analysis.

im not exactly sure what you are looking for us to say?

of course it would be awesome for someone to map the ball python genome. since you already apparently have a means to get dna into digital form, you already have one obstacle out of the way. some questions I would ask are how long does it even take to get one snakes dna into a database. just a quick look around on google is showing me humans take about 3 days. With that in mind how many normal snakes are you going to have to test before you can compare them to morphs to see where these alleles sit? I mean are we looking at a possible multi year project before you have the data you need?

It wouldn't be only testing hets, you could also end the lesser/butter debate and the cinny/black pastel debate, see what other morphs are actually the same, see what morphs lay on the same locus. Theres a lot we could get from this, but as you see above there concerns of money and also time.

Is this a appealing service for you? Why? Why not? What else would you want out of it?

I am working on targeting a specific section of DNA, not mapping the entire genome. By targeting a specific sections, a benchmark will be generated and can be used for comparison.

I am still working on setting up trials to determine turnaround time. There are a lot of factors that influence turnaround time including, sample type (swab or blood), DNA concentration for PCR (DNA replication) and then the actual protocol for running the sample. I am estimating that given basic constraints turnaround would be 1-2 days for digital results and 7-10 days for prints. With that being said, this is still only speculative until trials have been run and the protocol has been optimized.

i obviously have no idea how any of this works, but how exactly can you target a section and know that is where you should be looking.

Well the short answer is Sanger Sequencing.

I will have to identify which chain terminating variant is best for comparison purposes through accumulation and analysis. Once a sample is amplified using PCR then all 4 chain terminating variants will be introduced and then the results will be run through electrophoresis and the sequence will be deduced from there.

From that point on the same chain terminating variant can be introduced and then compared to the same section in the catalog to confirm a relationship between samples.

im more referring to theory, like how do you target where the albino gene resides. is it basically get enough data from normals together and then test an albino and hope your looking in the right area? im just not understanding if you don't first map the entire genome, how do you know the albino gene doesn't actually reside in the area your not looking.
