Is inbreeding responsible for the amount of colour phases in cornsnakes and kingsnakes etc? or is it just selective breeding.I assume a cross/inbred trait was found and then would subsequent breeding of the animal involve a fresh gene pool or crossing with a related snake with a same trait, my genetic knowledge is obviously limited, I am just trying to breed corns that are unrelated for a true? phase mostly Miami phases but only with other Miamis im searching for the best traits for parent snakes.
Please can anyone explain what a "1.1 king cobra is, does it explain its parenting im really not sure. I know this sounds ignorant or ill informed but i am just trying to expand my knowledge of snakes and this is a "grey" area 4 me. Thanks Kieron.

Kieron: When someone posts 1.1 king cobra, they are talking about two snakes. One male, and one female. If it were 1.0 then they would be listing one male. It if were 0.1 then they would be listing one female. And a listing of 0.0.12 means they have 12 unknown sex king cobras, usually young, but could be unsexed adults. JohnZ

Kieron: As far as the selective breeding verses inbreeding, well, king snakes and corn snakes both have large ranges, with a lot of color variations over the range. For instance, there is what is known as a Okatee Corn that is typically patternedl from a very small area of South Carolina. Same thing applys to Okefenokee swamp. The corn snakes there are distinctive, just as the ones from Ocala Florida. Basically, you have disjunct populations that are isolated by land forms, or river systems, or other geographic barriers, that cause snakes in one area to be somewhat isolated, and thus somewhat inbread, and thus simmilar looking over time. Same with kings and corns.
However, some of the commercial snakes have also been selectivily breed by humans to bring out certain color / pattern charistics.
So, the color differences in kings and corns is both selective and inbreed, depending on wether the snake was wild caught or captive bread and manipulated.
Hope this helps some. JohnZ

Hi mate there are advantages and disadvantages to inbreeding .
The advantages are that :
Produces uniform or predictable offspring.
Hidden (recessive) genes show up and can be eliminated.
Individuals will "breed true" and are "pure."
Doubles up good genes.
Eliminates unwanted traits.
The disadvantages are:
Doubles up on faults and weaknesses.
Progressive loss of vigor and immune response.
Increased reproductive failures, fewer offspring.
Emphasis on appearance means accidental loss of "good" genes for other attributes.
Genetically impoverished individuals.
that should give ya some ideas anyway

Some color morphs are simply a function of breeding different existing populations to get something in between. This can be done in one generation but usually doesn't make for anything that unusual.
The most interesting morphs usually descend from a single aberrant, naturally occurring individual (albinos and such). In my opinion the best way to breed them would be to introduce new blood at each generation, but it's quicker to breed siblings back to eachother or even offspring back to their parents, so that's what I think most people tend to do, at least for the first few generations. I guess I can understand because the real money is in the first few generations before everyone is breeding them from your offspring...

Well, there are alot if inbreeders in the business. But it does not only apply for reptiles. If you go to West Virginia and Kentucky, you will find alot of people who are inbred. They usually have a football shaped head, pasty skin, 4 teeth at the most,skanty body hair, and usually have speech inpediments. There IQ runs around 40 I think. So, the term retarded comes into play. Also have alot of inbreeds in Georgia and Alabama also. But I am not one to judge, I love retards just as much as anyone else. They make me laugh. They catch bugs and give strangers big ol hugs. If you ever come to the states, espically the south, and you hear dueling banjos.. RUN......... And hold you ass when you are running. Dont ask me how I know. Signed::: Concerned member.
