If you have a blood transfusion,do you get the other persons DNA?Would you then have 2 DNA's?

Since you would have more of your DNA than the transfused blood your blood would convert the DNA into yours.

When I first gave blood, they sent me a donor's card that told me my blood type.  And then they told me on every piece of mail they ever sent me after that.  D@mn type O universal donor nonsense!  They don't tell you right away, though, because they don't do any sort of testing (other than the anemia one) on your blood there.  It takes awhile.  But they do send you something.\n\nYou aren't supposed to give more blood for a couple of months after you donate.  Doctor's offices do take a pretty small sample, though.  However, just to be safe, I'd wait to give until after the physical, and ask my doctor while I was there.

They have to do this because only certain parts of DNA are used to ID people. And so much of DNA is similar they prove identity with statistics. So the likelihood of the DNA being the specific person is 1 in 20000 and that linked with other evidence is often more than enough to prove guilt or whatever. There is a law of probability and when things are put together it is very reliable.\n\nOk I am adding on in response to your question. I have consulted a textbook and think that the test described above is pretty conclusive. The textbook describes running a gel with the DNA fragments on it. They space out and are very obviously different to each other and are compared to the original. (see example of gel here http://gallery.hd.org/_c/natural-science/_more1999/_more05/DNA-genetic-fingerprinting-dark-bands-in-gel-are-almost-unique-for-a-given-individual-tweaked-1-AJHD.jpg.html) . Another thing mentioned in my textbook is taking samples from commnunities to compare blood samples. So one could suggest that they took samples of blood from 20000 people in the neighbourhood and only the one persons blood dna fingerprint matched up.

No. A baby gets his DNA from mom and dad. Dad contributes 1/2 mom contributes 1/2. (Yes, this a simplified answer.)\n\nDNA testing can prove paternity because it looks for genetic markers that come from the dad.

it is very simple \nif ur blood type is o+ than u can receive blood from o+ and o-\nif ur blood type is o- than u can only receive blood from O-

Twin to twin transfusion is not to be confused with two babies sharing a placenta.  Identical twins share a placenta, and there are no health risks to mother or babies.\n\nTwin to twin transfusion is where instead of both twins sharing a placenta, one twin gets all the nutrients from the other twin.  It's a very serious condition, and if detected early enough in the pregnancy, women are often informed about abortion.  If it's not detected early enough, or if the mother doesn't wish to have an abortion, then the twin that gets the nutrition from the placenta may have a chance of survival.  The one who gets all the nutrition from its twin is likely malformed and underdeveloped, and is incredibly unlikely to survive at all.

The cells from two separate eggs (twins) can combine into one whilst in the mother's womb - thus one child is born but has two dna's instead of one

There is about a 1 in 10 billion chance that someone would have the same dna as you, unless you have an identical twin.  Scienctists don't like to say "never", but that's really close.

It is because they want to make sure that the blood is there for them. The blood type is a perfect match for them because the blood is their's. Also, people with rare blood types do it so they would have the blood they need. They don't have to risk anything with a different blood type that could damage them or even kill them.

Yes, it is possible for a DNA test to be wrong when either the mother of her child(or both, but that is extremely rare) is a chimera. Chimerism occurs when two or more embryos fuse together in the womb. Scientist are not sure why, but these embryos form the different parts of the baby's body, resulting in different parts of the body having different DNA. Therefore, a woman's blood DNA can be different from the DNA in her thyroid, reproductive organs, etc. When DNA tests are performed later, the DNA may not match because of the child's DNA would match that of their mother's reproductive organs, and the DNA tested may be taken from the blood or a cheek swab. The only way to diagnose chimerism is for a DNA test to come up wrong, those results to be appealed, and the different organs of the body to be retested several times. Chimerism is extremely rare, and that one of the few instances when DNA tests can be wrong between people who are known to be related.

The transfused blood would contain the donors DNA only if it contained white blood cells. When they test your DNA they take the sample from the inside of your mouth (bucal smear). Nothing to worry about.

yes\notherwise known as universal donor\na person with this blood type could only take blood from exact same group.\n\nab+  universal recipient =  can take blood from any group but can give blood only to same group.

There are certain identifiable characteristics that can be found in some blood samples. The most prominent example is Sickle Cell anemia.  \nThat's just from blood. However, from DNA markers, it is possible to identify certain genomes that would give you a pre-disposition to certain races.  It may not be a definative race, but it could narrow down possibilities until you can come up with a high probability.

ofcourse, using any other Body cell. every cell has DNA

yes\n\none parent is blood type A+, and the other is B+.\n\nTherefore, can be represented as AO, and BO.\n\nin this way, it is possible to have an AB, AO, BO, and OO blood type, more commonly known as AB, A, B, and O

This is called Chimera. After the mythological beast which had body parts of different sets of animals.\nA Chimera will usually have their blood and tissue of one DNA, while their reproductive organs and some inner organs will be of another. This is fairly random as to the "where" and "what," and it usually comes up as a concern in DNA testing when a mother is seemingly not the parent of her child. Or in crime cases where they cannot identify the rapist based on semen.\nThis condition occurs when two twins are begining to form within the womb, and for whatever reason one twin dies--and the other cell takes on the DNA--as a "clean up" if you will. The result is that the one cell finds no reason not to use the perfectly good DNA, and incorporates both wherever it sees fit.

MOST blood is transfused as pRBC's (packed red blood cells). Red blood cells have no nucleus, and therefore carry no DNA. \n\nRarely whole blood is transfused which contains DNA carrying white blood cells, usually have too many cell surface proteins that are recognized as not self (or foreign) and are destroyed.
