i know the basics about genetics but i was looking around the internet last night and on the NERD sight and saw all the different ball pythons they had and i was wondering exactly how is a certain trait like the caramel albino ball python started...is it just chance and after that you can just carry it on like albinism or is their another way...and has anyone bred an alby copper yet....i have seen cottons but not a copper....im gonna try and mess around with rattlers next year and im starting with albinos...hopefully

I am sure there are some albino coppers somewhere, i havent found them yet. To my knowledge the chances of albinism increase when offspring are bred back to parents, i know its not the same for all traits it just depends on where the trait is located and whether it s dominant or recessive. A very intelligent way to find out if something is in fact genetic (striping, albinism, leucistic) is to have the DNA in the blood sample sequenced, and that way it will be easier to determine where the trait is located and if it can be carried to the next generation. Not to toot my horn, but this is the type of genetics I work with. I am in the process of obtaining samples from my collection to get sequenced here in our lab (as i work for a global genetics company) to determine what traits are hereditary and where they are located in the genome. Some traits ( I have seen hypo praries, that where really just very light S texas praries) have yet to be determined (ok many) and alot of people out there will tell you they have something thats hypo or whatever, when the bloodline has never been tested. Traits like melanism and "blond" are sometimes natural traits (like in black C.horridus) which are mainly dependent on the animals habitat (higher vs lower elevations) and not always genetic. But until someone starts a genome library on venomous snakes (and each would have to be specific for each ssp) then many of these traits remain unproven. I guess what I'm sayin is it involves alot of time, and a little luck as well. But frankly, it is gonna be a LONG WHILE before hot snakes are sequenced, heck most researchers are still working with lower level forms like zebrafish and plant sequencing. hope it helps,
