There is an actual condition called chimeraism. It's the result of two fraternal twins joining and one being absorbed by the other. The surviving twin then has two DNA types. You may get one DNA strand from semen, and a different strand from a blood test.

Those people who have two types of DNA in their body are called chimeras after the mythological creature with a head of lion, body of a goat and a tail of a serpent. These people are sometimes also referred to as mosaics. It has found that these people have two different types of DNA in various parts of their body. Though a rare occurrence, this could have been due to various reasons. [Vladar, 2004]

One of the common reasons is that chimeras are formed if developing fraternal twin embryos join together to become one embryo. This is something which is completely opposite of identical twins who are formed when a single embryo splits into two. This occurrence takes place in the very early stages of the embryo development i.e. when it is still in the form of unspecialized cells, so when it develops the baby that is born is healthy but with two types of DNAs. It is also found that fraternal twins don’t have same set of DNA, however, they the two fraternal twin embryos fuse together it results in chimera.

Another reason for chimeras to form is when developing fraternal twin share the same blood supply. This usually happens when the twins with different DNA share a placenta in the mother’s womb and cells from their blood mix together. This results in the twins being chimeras based on only their blood as other cells are not affected by the blood supply. Chimeras are also formed through some mistakes or mutations taking place in the division of the cells in the development embryo. This mainly takes place when the cells split into two so that they are able to be formed into more of themselves for the growth of the embryo. It also results in the the doubling up of the DNA by the cells which gets divided between the two new halves. During this process, if something goes wrong, then some new cells result in having different DNA. If this happens in the early stages of the development, then the tissues which are developed from the cells will have different genotype.

Just look at The Lord of the Flies. Poor piggy wasn't even genetically enhanced to be a pig person, he was just a person. And those damn hunters still wanted to kill him more than they wanted to kill a boar!

If it is okay to kill a pig to harvest the organ to save a human, why is it not okay to kill a human to harvest the organ to save a pig? Let's take this whole Genetic thing further!

We could have entire 'Zoos' housing certain type of Donors. Donkeys that have mouse, cat, dog, human, zebra organs. Fish that have spider, butterfly, and reindeer parts. Humans that have elephant, rhino, and whale parts.

Then we'd just kill the donors when some poor creature needed a part! Why just save humanity when we can play God and save all the world! Why just slaughter pigs and horses when we can chop up a few martyrs of our own to save some poor animals? Hell, we kill them to save us, why can't we be fair and return the favor?

Or we could take an Elephant, Rhino, Skunk and a Porcupine, mix them with a Whale and a Condor, and have an elite trainable weapon! Hell, maybe even give it shark teeth! It could be the ultimate killing weapon! Perhaps a venomous bite like a Snake? What a great destructive weapon that would be! Like when the Nazi's tried making Shark People for nautical soldiers, but way more cooler than that lame attempt!

I mean, after all, we have the Science and Technology now! Imagine all the things we can do!

Damndest thing about Pandora's Box, open it and the bi-yatch doesn't close. (Edited to slightly obscure vulgar language. Mods, feel free to edit again if need be. Sorry, got a little wired up there!)

Would you not want this as a pet???



Seriously though, youve got to think, is there realllllly that much point of making human mouse hybrids or whatever. Is it REAAAAALLLLLLYYYYY that important? It just seems that, they have one perfectly good method to say, produce new organs for people, but since thy have the technology at their disposal, they cant resist doing it because they can.
