I disagree...

Let's take a real-life example about which there should be little debate:

My mother has blue eyes. My father has brown eyes. I have brown eyes. Since my mother has blue eyes, I have 1 allele for blue eyes, but the allele for brown eyes that I inherited from my father is dominant to the blue allele.

My wife has blue eyes and so does our son. What this means is that our son inherited a blue allele from my wife (she has 2 blue alleles) and he inherited a blue allele from me.

Using your logic, I am 50% blue-eyed and 50% brown-eyed. Continuing with your logic, since my wife is blue-eyed our son should be 25% brown-eyed and 75% blue-eyed. In reality, this is not the case...our son is 100% blue-eyed.

Statistically, I would agree that "on average" any offspring from my wife and eye would be 75% blue-eyed and 25% brown-eyed. From a practical perspective, however, they will either be blue-eyed or brown-eyed. Any blue-eyed offspring are 100% blue-eyed. Any brown-eyed offspring are 50% blue-eyed and 50% brown-eyed. Using your logic, this is impossible. Using your logic, all offspring should be 25% brown-eyed and 75% blue-eyed.

Having said that, I would like to address a couple of specific comments that you made in your reply:

"your F2 animals receive 75% genetic material of ball python ancestry and 25% genetic material of angolan ancestry."
The Angolan Ball is an F1 generation. To produce an F2 generation, you must breed F1-generation animals together. A successful breeding of an Angolan Ball to an Angolan Ball would result in F2 offspring. Our animals are not F2 animals.

"to state anything else is misrepresentation."
We are not selling these animals. I stated that our beliefs regarding the genetics of these animals were exactly that - our beliefs. I am not sure how you can interpret this to be "misrepresentation".

"however, there really is no room for debate or interpretation in this."
I disagree. I feel that I have already explained why your theory of "25% Angolan 75% Ball" does not hold up from a genetics perspective. I would certainly like to hear the basis for your position that "there is no room for debate or interpretation". Why does your theory so readily fall apart in the example of blue and brown eyes that I gave above? I would certainly like to hear your explanation for how my blue-eyed son is somehow made up of 25% brown-eyed genetic material.
