is it possible for any two people to have the same DNA

- Not even identical twins have the same DNA--although theirs would be far closer than anyone else's. DNA changes over time. Odds of two siblings having the same DNA who did not split from the same zygote are vanishingly small.

How is it that do siblings taking the same ancestral dna test get different results? DNA Tribes is correct that siblings can and do have very diverse DNA. Your autosomal DNA is a random subset of your mother's and father's DNA (50% from each parent). Two siblings will not have the same results for the same reason that they do not look exactly the same. They do not get the exact same 50% from each parent. Even identical twins don't have exactly the same DNA (only almost exactly the same).

- Culturally they may each say they are “1/8th Cherokee” but at the DNA level, one may have no Cherokee DNA at all. So yes, it is definitely possible for two siblings to get pretty different ancestry results from a DNA test. Even when they share the same parents.

- September 1, 2015. It seems like brothers and sisters should have the same ancestry background. After all, they both got half their DNA from mom and half from dad. But because of how DNA is passed on, it is possible for two siblings to have some big differences in their ancestry at the DNA level.

Can two brothers have similar dna? Only if they are IDENTICAL (Medical term) twins will they have the SAME DNA. Not all twins are identical. Non identical twins have SIMILAR DNA but just only like any other sibblings ( around 50%). Complex subject as Genotype and phenotype come into play.

- The only exception is identical twins, who share 100% of their DNA. Each human cell contains three billion DNA base pairs. Our unique DNA, 0.1% of 3 billion, amounts to 3 million base pairs. That's more than enough to provide a profile that accurately identifies a person. DNA is often left behind at a crime scene. It is present in all kinds of evidence, including blood, hair, skin, saliva, and semen. Scientists can analyze the DNA in evidence samples to see if it matches a suspect's DNA.

- Humans share the same set of genes but not necessarily the same form of those genes. Different forms of genes called alleles allow us to have different traits such … as attached earlobes versus unattached earlobes.here may be some DNA in some dirt samples, but this DNA does not belong to the dirt, rather to something that has somehow deposited its DNA into/onto the dirt, likely through decomposition. If dirt had DNA, and that DNA had the same properties as human DNA, then dirt would look exactly like humans.

Twin Tests Identical twins have exactly the same DNA. They will be the same sex and they are more likely to look like each other. Fraternal or non-identical twins develop from two separate fertilized eggs. Non-identical twins will share on average half of their DNA, similar to the percentage of DNA shared by two siblings who are not twins. Fraternal twins can be the same or different genders.

DNA profiling Although 99.9% of human DNA sequences are the same in every person, enough of the DNA is different that it is possible to distinguish one individual from another, unless they are monozygotic (identical) twins.ach person’s DNA contains two copies of these markers—one copy inherited from the father and one from the mother. Within a population, the markers at each person’s DNA location could differ in length and sometimes sequence, depending on the markers inherited from the parents.

- Even though Stan and Pierce do not have the same copies of each of the markers, they both always have one marker from their mom and one marker from their dad. Which means they are almost certainly brothers. So there you have it. With simple DNA tests, siblings can match at any number of markers. They can match at all, none, or somewhere in between. This has nothing to do with how related they actually are at the DNA level. Siblings are about 50% related.

Can DNA Prove the Existence of an Intelligent Designer? Because your parents are 99.9% the same, any DNA you get from them is 99.9% the same too. So really, when we are looking at how similar you are to your parents, we only need to look at the 0.1% difference. Now, this sounds kind of weird, but stay with me. Your genes are an average of your mom and dad's genes.

Question: Can two people who are not twins nave the same DNA No two people who aren’t twins won’t have the same DNA, in fact even twins don’t have the same DNA. Non-identical twins have about 50% of the same DNA, which makes them no more related than any other siblings.That’s because they come from separate fertilised eggs (so two separate egg cells and two separate sperm cells).

The Claim: Identical Twins Have Identical DNA The Claim: Identical Twins Have Identical DNA. It is a basic tenet of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and, thus, share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not. The discovery opens a new understanding of why two people who hail from the same embryo can differ in phenotype, as biologists refer to a person’s physical manifestation.

Why do my brother and I have different DNA? No two people have the same exact DNA, with the exception of identical twins. However, of all the people in the world, the person that is related the most to you, scientifically speaking, is any sibling of yours. They are 99% alike to you. That 1% is some other alleles that are different between you and them.

DNA profiling The DNA test report in other family relationship tests, such as grandparentage and siblingship tests, is similar to a paternity test report. Instead of the Combined Paternity Index, a different value, such as a Siblingship Index, is reported.lthough 99.9% of human DNA sequences are the same in every person, enough of the DNA is different that it is possible to distinguish one individual from another, unless they are monozygotic (identical) twins.

Humans, Chimps Not as Closely Related as Thought? The DNA data proved that humans and chimps are more closely related to one another than either is to the gorilla. Using the more sophisticated methods that became available in the 1980s and 1990s, scientists revisited the question of how much DNA humans and chimps share, and came to similar conclusions.

We Found the Gene! Huntingtonâs Disease After the Cheering    Some 90+% or so of human DNA is the same between members of the  same species, but in a single human body--We have two copies of  each chromosome, two copies of every gene, and it is possible to  have two copies of the same allele.here may be some DNA in some dirt samples, but this DNA does not belong to the dirt, rather to something that has somehow deposited its DNA into/onto the dirt, likely through decomposition.

Can two people have the same dna? They can but it's improbable the number of possible dnas is 20^200, that is a big *** number, so that should make very improbable that two persons actually have the same dna. Renegado · 10 years ago. Thumbs up.

- The only difference is the order of the base pairs. Like in fingerprinting, there are so many millions of base pairs in everyone s DNA that every person has a unique sequence.Every person could be identified using the sequence of their base pairs.However, there are so many base pairs in every person that this would be very time consuming.Repeating patterns in DNA allow scientists to use a much shorter method.very person could be identified using the sequence of their base pairs.

Can two people have the same dna? Twins is not an accurate answer. There are two types of twins 1. Identical twins 2. Ferternal twins Only Identicl twins will have same dna structure.

What About the Similarity Between Human and Chimp DNA? This, of course, does not mesh with Genesis 1–2. Evolutionists frequently assert that the similarity in DNA sequences provides evidence that all organisms (especially humans and chimps) are descended from a common ancestor. However, DNA similarity could just as easily be explained as the result of a common Creator.his, of course, does not mesh with Genesis 1–2.

- Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people.lleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features. Genes are made up of DNA.
