there is a name for people whom carry two DNA what is it and how do I research it?

It is called Chimira(sp) one twin is absorbed into another and usually it is the semen or egg that has the different DNA.  the Saliva and blood are the actual person's DNA and the other is like a brother or sisters DNA

If the DNA samples applied to the autoradiogram come from both parents and the child, try comparing the distance traveled child's DNA fragments to that of both the mother and father.  There should be commonality to some degree if there is a relationship.  The more markers in common, the more likely the sire.

They get DNA from nucleated cells like white blood cells (in blood and saliva) and epithelial cells (in saliva). They lyze the cells to free the DNA, centrifuge and take the fraction with the DNA, treat and amplify or multiply the DNA fragments, put markers or specific labels, determine the presence and amount of this marked or labeled fragments, and compare the distribution with known samples or DNA database. DNA results are usually one page long.

First off, the genes are not new.  They've been around for years, we're just trying to figure out what they are.\n\nSo, suppose you're looking for the gene that gives people nipples.  How do you know, out of the billions and billions of genes people have, which one codes for nipples?\n\nWell, first, you look for someone who is born without nipples.  Presumably, someone born without nipples either is missing the nipple gene, or has a nipple gene that is all messed up.\n\nNow, you can scan the DNA of the person without nipples, and see what's so different in their DNA.  Eventually, you'll find a spot or two that's pretty unusual, and you can then guess that one of these weird spots is probably the nipple gene.\n\nIf this particular part of the DNA sequence is similar in humans and lab rats, you can then fiddle with lab rat DNA in the spots that the no-nipple people have differences, and eventually you should come up with rats that have no nipples, or really weird nipples, and TA DA!  You've used functional screening (by screening out a normally functional gene) to determine where the nipple gene is.

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.

A person who is a chimera is made up of cells from different people. So some of their cells have the DNA of one person and the other cells have the DNA of another person. How do you do that? \n\nImagine that inside of a womb, instead of there being only one egg, there are actually two. If both of these eggs get fertilized by two different sperm cells, you get fraternal twins. Fraternal twins are no more related than any brother or sister. \n\nNow, imagine that instead of developing separately, these fertilized eggs actually fuse. Then only one baby would develop. This baby would have cells from not one, but two different zygotes. \n\nevery zygote carries its own unique set of DNA. So the baby would have two different sets of DNA. Most chimeras grow up and look like everyone else. You probably wouldn’t be able to tell that the person was a chimera. Sometimes you can see patchy areas on the skin or two different colored eyes.

Try the Human Genome Project\nThere is some other project where you send them a splot of your blood and they tell you your entire family history and migration patterns and everything.\nIt's called genetic anthropology.\n\nSome scientists now believe that everyone can be traced back to 4 major groups of people or something like that.\n\nHere's the only link I found but there are better ones out there.

That would be a violation of HIPPA, which provides protection for our medical records. I do believe that law enforcement officials can search for DNA matches of those who have given samples, but civilians cannot and, I believe, should not be able to. Your DNA is similar to those you are related to: your mother, father, siblings. Humans also share basic DNA sequences.

it is all in the dna,

It's Deoxyribonucleic acid.

well, its a little more complicated than the above person mentions.\n\nAside from finding the right person to do so the process is listed below:\n1)  Restriction Enzymes break apart several parts of your DNA\n2) All the DNA sequences are put into a microfilament inside a gel.\n3) The gel is attached to an anode and a cathode at one end.\n4) the heavier and more electronexgative pieces move to the anode.\n5) this gives you a unique fingerprinting of your dna. The end result is a bunch of lines on gel which is unique to yourself.\n\nIf you want to get the sequences of your DNA figured out the project is much more complicated and would take many many years. However, the human genome project did it. And since every person has a 1% difference in their alleles (that is right ONLY ONE PERCENT!) it is very similar. Moreover out of 1000 nucleotide bases in a sequence of a polypeptide or DNA, 999 are the same as any other given person. So essentially the human genome project maps your genome very very closely.

DNA is an abbreviation for Deoxyribonucleic Acid. \n A piece of a chromosome that dictates a particular trait is called a gene. \n Each DNA strand is 10 atoms wide. \n The DNA stands in your body stretched out would be about 500 million miles long. \n There are so many millions of base pairs in each person's DNA that every person has a different sequence

It was a Brittish scientist and unfortanately I can't remember his name. It was used as evidence the first time in a murder trail in England where two girls were found dead in a path near a field. The new science of Dna helped to prove whom the killer was. I even read the book about the murder investigation and the scientist but me with my middleage brain can not remember it's name either. Maybe someone out there can remember the name of the scientist or the  name of the book. Sorry I could not be of more help. But maybe this will put you on the right track

The genes are said to be "linked."

gel electrophoresis can be used in forensic science as well as in maternity@paternity testing.here wat they do is from the place where the crime has occured if they get some evidence like a bit of hair, or spitted saliva or a small amount of blood any thing else they usually collect these sample they usually extract dna,with tat they set@ioad    withsamples of that particular victim and they usualy have collection of samples from the crime they will run the sample of the victimie the criminal @those of with the suspect.usually in gels we get bands at particular position,if there are identical band found in any one of the suspect @the victim then he is the criminal.

Good God man you are on the net, you have more information than you know what to do with right at your finger tips. Go to Yahoo's main page and type genetics into the search bar.
