DNA, Chromosomes and Chimera talk

Though pretty unlikely, this could actually happen. It is similar to paradoxing or chimerism if not caused by them. I am recalling a person who had one set of genetic code on the exterior anatomy and entirely different set of genetic code for their internal organs. It seems weird that a vet would make this call with at least a little experience.

The thing is...this Vet made that determination after sexing the Ball Python.

How would they know that the "insides" are that of a Blood Python?? How is a Blood Python different on the inside ?

And how would you "know" that by sexing a baby snake?

I find that one of the more odd ones :)

Still wouldn't work, Even if you breed a blood to a ball the resulting DNA would be a mix of blood and ball. There wouldn't be blood parts and ball parts. Only blood/ball parts. So even a paradox from the pairing would be two separate blood/ball parts

This is interesting and I honestly would have not thought it was possible to have this type of hybrid without outward visual indicators, but at that level of genetics I am definitely in over my head. The stars that would have to align to make this possible I would think are very nearly statistically impossible though. We are talking a hybrid that is also albino with no external visual indicators. I would think that Z would see them if they were there. She has both species.

But I don't have the "inside / out" special !!! :rofl:


or...maybe I do and just don't know it...

Mixing is how genetic inheritance is supposed to occur, but that is not always the case as we see with Chimeras. There is no apparent rhyme or reason to how these genetic anomalies occur, like I said unlikely but not impossible.

I would assume there are some differences in genitalia as there are between many closely related species. Now the vet would need to have pretty vast experience with both, but it just doesn't add up to me why they would say that to suggest this otherwise. In all likelihood this came down to a miscommunication between a vet and the owner.

Still doesn't work like that. Chimeras are still part mommy part daddy in both "sections". However for the unlikely but not impossible scenario, it is possible the albino genes are the same in both species (like ball pythons and burms) so it might be possible to have a blood/ball albino paradox.

There is actually a case of a persons sex organs being of different genetics than the rest of her body. Her name was Lydia Fairchild and there was a whole interesting court cased involved for those who are interested.

By mixing I was more referring to phenotypical expression, for example a split faced cat or an animal that appears to be a ball with blood genitalia. Often a hybrid takes cues from one parent over the other. As we see in snakes you can actually get offspring that resemble each parent, which is why I went with the chimera theory. Thinking about this more though, you would not even need chimerism for this to happen as it simply could be a case of which phenotype is shown. A hybrid is not always a perfect mix of both animals but may take traits from either. Also we are assuming that snake hybrids are diploid when the fact that they are not generally sterile could point to polyploidy even further making this a possible situation. If this were the case then the possibility that a chimera that is genetically separate part ball and part blood actually do exist, although I will admit the probability is incredibly low.

I am fimilar with the case. All of her DNA is part mommy part daddy. It's not just the dad or just the mom. It is mixed. She just has different mixes of DNA in different areas. No different than me and my brother having different mixes of our mommy and daddy. Except those mixes are in one body. Chimeras are combined would be siblings, DNA works the same, just might be different in one area of the body vs another.

Yes one animals traits can dominant over another. I notice it seems any ball hybrid has a ball head. However the pattern and body makes it obvious to what it was mixed with. There have been quite a few blood balls aka superball. None I've seen could be mistaken for just a ball.

So even in polypoid situation, which btw is a huge leap imo, the resulting chimera would still have 2 separate DNA that are both the mix of mommy and daddy.

I am aware the genetics are mixed code from each parent in a chimera, but phenotypic expression is not necessarily. Phenotype is what we are talking about in this situation, no? I explained my train of thought with different looking siblings being combined into a chimera, so I am not sure why you are still bringing up mixed genetic code. Am I missing something?

It could be that no one is advertising the more plain hatchlings. Here is a mix that is exactly opposite of what you have described head of a blood, pattern of a ball. http://s218.photobucket.com/user/abi...rball.jpg.html

Diploid means two chromosomes, one from each parent containing genetic code or DNA. Each chromosome is composed of two strands of DNA so that means four DNA to a set. Polyploid is having more than a single set from each parent, usually double so 4 chromosomes or 8 strands of DNA. Out of the 4 one matching pair is allowed to pair during meiosis creating essentially cloned DNA, but each chromosome pair is not from the same parent. It may be unlikely that this is possible because it is thought that homoploid hybrids are more common in animals, but not many studies have been done on hybrid genetics in animals.
