What is the difference between clones and identical twins?  Would clones have identical fingerprints?

A very good question from your nephew\nNature provides us with the natural form of clones:\nidentical twins share the same genetic makeup and even\ndeveloped in the same uterus. Nevertheless, their\nfingerprints are not identical, though similar. The\nformation of fingerprints is partly the result of a\nstochastic process.\nThe ultimate shape of fingerprints are believed to be influenced by environmental factors during pregnancy, like nutrition, blood pressure, position in the womb and the growth rate of the fingers at the end of the first trimester. \n\n\nSo identical twins and clones are similar and they have similar but not identical finger prints.

No you could  not have 4 identical twins.  Twins are two babies born at once.  at conception the egg splits and makes twins they share the exact same DNA there for can not go to prison based on DNA evidence.  On the other hand it is very very rare that you would get quadruplets that are identical but it is possible.  If they are all the same sex it may be the case.  I have a relative who has 2 sets of twins 10 months apart and they all look identical however they are not as it is impossible.  Hope this helps.  I come from a family with 17 sets of twins.  They say that it skips a generation however that is not always the case.

A 'person' is identical to another 'person' if both consciousnesses encode the same information and follow the same process of consciousness, with the same sensory input.\n\nImagine instead of changing hair colour, the genetic change is a single nucleotide on a part of your DNA that has no effect on the functioning of your brain (literally no effect), then you as a person would theoretically develop exactly the same information in your brain, and your brain would function exactly the same, and your senses would be exactly the same, so you would be identical people.\n\nInterestingly, if you were a geneticist and examined the sequence of your own DNA, and looked at the nucleotide that is different (say G vs. T), then at that instant, your mind would no longer be identical to your 'other self's' mind, although they would be very very similar. And again, continuity has nothing to do with it.\n\n've also heard this 'Doppleganger theory'. I don't think that it it likely for the following reason: It is assumed that if we take a given individual and contrast that with the number of people on the planet that statistically speaking there should be a person who looks the same. However, this theory says a bit more than that- it says that every individual has a twin. So if you thought that a single person having a twin was unlikely, then just imagine the probablity that everyone has a twin.\n\nIn any case so what if we have a twin? I'm not sure that it would make any real difference to our lives. Moreover, if by twin we mean someone who looks like you then how precise does that similarity need to be? After all, they may have the same facial features as me, but they might have a different skin-colour, or maybe they have one leg shorter than the other.

Identical twins are identical because the egg splits. Fraternal twins are not identical and are formed from different eggs.

Hi! I'm the mother of identical twins.  Here's some facts:\n\n1. Identical twins occur when one fertilized egg splits.  It's a random act of nature and is not impacted by family history, age, ethnicity or fertility drugs.  Every pregnancy has a 1 in 250 chance of being identical twins.  Identical twins have the exact same DNA.\n\n2. Fraternal twins occur when the female produces two eggs and both are fertilized.  It can be influenced by family history or fertility drugs.  Advanced age or certain ethnicities also increase your chance of fraternal twins.  Fraternal twins are essentially brothers/sisters who happen to be born at the same time.  \n\nHope this helps.

In identical twins one is is a natural clone of the other.  If science ever really created an artificial clone, it would have the same right to life as anyone else.  But I do not expect a responsible scientist to do that.  What they're up to is creating stem cells for use in curing a variety of diseases.  Those who oppose this are phonies about their respect for life.

No, fraternal twins have DNA that is as similar as brother and sister would be.  That's essential what they are, brother and sister (or sisters, or brothers), but simply born at the same time, since it is two separate eggs being fertilized by two separate sperm.

Well, technically identical twins are clones and many organisms with asexual reproduction clone themselves, so yes. I think the question should be if an artificial clone can reproduce; but most of them don't even live more than a few days.

The kind of files do not matter to when trying to determine if they have been modified.   The obvious solution that insure that they are absolutely identical are to open them both and read them byte by byte and make sure they are the same all along.\n\nThat's not that bad if you compare only one pair of files, but obviously if you have many pair to do, It can be a bit long...\n\nTo speed up the process, you can use hash values.  It consist of computing a value that take into account each bye of the original files and store those somewhere.  (Look for CRC for ways to do that)  You then repeat the process on the final file and make sure it still compute to the same value.

First, clones have been around for a long time - they can occur naturally. Identical twins or triplets start off with the same DNA and are considered clones of each other. There are many species of animal, including humans, where twinning naturally occurs.\n\nSome species, of both plant and animal, have been bred for so long to contain the same genetic material (useful for genetic studies) that each generation has the exact same DNA as its parents. While regular reproduction occurs, since the source material is the same, there ends up being no genetic variation, except for mutation.\n\nAs for artificial cloning, that has been developed in the past two decades. In 1997, Scottish researched announced that they had successfully taken genetic material from an adult ewe (female sheep) and inserted it into an egg cell that was implanted into another sheep who gave birth to the clone (Dolly the sheep), in a process called 'somatic cell nuclear transfer'. Since Dolly, several other mammals have been cloned. Because the transfered adult nuclei don't always take well with the hosting egg cells, there are many egg cells that don't develop clones than there are successful cloning attempts.

There are four basic patterns used to classify fingerprints -the arch, the loop and the whorl, and the composite (which is a combination of the arch, loop and whorl). If you think of a military map or a bushwalker's map, an "arch" is a gentle rise, a "loop" is a ridge, while a "whorl" is a solitary hill or peak.\nTo match one fingerprint to another fingerprint, the fingerprint officer has to find a certain number of recognisable features that are the same in each fingerprint - these are called similarities. In most countries, there have to be more than eight such similarities between the fingerprints, before they can be counted as admissible evidence.\n\nIdentical twins happen when a single fertilized egg splits into two embryos. Each of the embryos has identical DNA, so surely the new-born babies should greet the world with identical fingerprints?\nFingerprints are laid down between the 13th and the 19th week of growth in the womb. There are at least two factors that can give different fingerprints.\n\nFirst, the DNA doesn't make a perfect copy of itself every time it divides - it picks up mutations. To get from one single cell to the 10-100 trillion cells of a grown adult human, the DNA has to divide many many times. This gives ample opportunity for many mutations to accumulate.\nSecond, the mathematicians tell us that if the foetus had flattened finger pads, the baby is more likely to have the simpler arch pattern, or the slightly more complicated loop pattern. But on the other hand, if the foetus had swollen finger pads, baby is more likely to have the more complex whorl pattern of ridges. The two identical twins might grow in the same uterus, but they have different lengths and diameters of umbilical cord, so they will each get a different blood flow. The twin with the lesser blood flow will cut down the blood flow to the lower body, to preserve it for the brain. By an accident of anatomy, this gives more blood flowing into the arms. The baby ends up with proportionately bigger fingers, and more whorls in their fingerprints.\n\nIn 2003, a paper called On the similarity of identical twin fingerprints was published in The Journal of the Pattern Recognition Society. They found that the fingerprints of 94 "identical" twins were not identical - although they were more similar than non-related people. \nVarious organisations collect fingerprints, but the FBI probably has the biggest collection. They have over 200 million sets of fingerprints - but then, so does every house with small children!

I'm assuming you mean identical twins?  I have identical twins and was discussing this with a friend of mine who is an identical twin.\n\nIdentical, or monozygotic, twins come from the same fertilized egg which splits.  They have the exact same DNA.  So, if a set of identical female twins were to have children with a set of identical male twins then the resulting children would genetically be brothers/sisters.  (Emotionally/legally/etc they would be cousins.) They would look as similiar as other sibilings do.\n\nMy identical twin friend said her and her sister used to want to marry identical twins just to see what would happen.

no....the clone is started with a single cell.....the dna is removed from one cell of the donor and place into the cell of a uterine egg cell.  The new cell is then zapped with low amounts of electricity to get the dna to start doing its job of replicating.....since the dna used is a blue print of what the makes up the  donor the new egg will develop into an identical image of the original.  But will be a younger version if it lives.....this process must be done hundreds of times if not more to get even one cell that survives the process and can live/replicate the way it should.

Well there are so many technicalities revolving around this question. While biologically speaking you could call the children sibblings is erelevant to the question. Manly because they will have there own genetic codes.  That is where this becomes quite complicated because genetics deals with more than just genes it deals with traits, DNA, Chromosomes, Blood Types, etc...  As far as them being related, coming from not only the same father, but an identical twin they are going to have very similar genes.  In fact when it comes to there family traits it will be identical.  However no individual, no matter if they are identical will ever have the exact same genetics (in the broad since) as another because that would go against the natural law of diversity.  So sumary exact same family traits, but overall two different people (genetics).

Identical twins have identical DNA. They come from the same fertilized egg, which had only one complete set of DNA in the first place. That fertilized egg and its single set of DNA split to form twin embryos-each with its own set of DNA, identical to the other. One small quibble: the DNA sets will be identical, unless one fertilized egg's DNA mutates. Such mutations, however, are normally so tiny that DNA analysis can't detect them

No, identical twins are nearly identical in DNA-the only differences are in parts of the randomly sorted genes, and those would be different in the child as well, so couldn't be used for testing.

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.
