Then siblings have the same DNA?
815639
DNA is in chromosomes. Chromosomes are in 23 pairs: 2 *different* copies of Chromosome 1, 2 different copies of C2, etc, in each person.  Whether you get your father's Chromosome 1 that he got from his mother, or the one he got from his father, is random with respect to which Chromosome 2 you get from your father. Same goes for your siblings. The chances of two nontwin siblings getting the same exact set of 23 5chromosomes from one parent are vanishingly small. The chances of siblings getting the same exact set of 23 chromosomes from EACH parent are .. well, it's essentially impossible. \n\nSame goes for the possibility that they would receive NO chromosomes in common - although it is theoretically possible to have siblings that share no genetic relation at all.\n\nDNA evidence is never 100% conclusive, but the tests that are widely used (if done properly) have such a small possibility of being wrong that they might as well be 100% conclusive. That's because there's just so much genetic material in any one person, it averages out ... makes it so that siblings are actually very close to 50% alike - even though they could be anywhere from 0 to 0% alike, in theory.

Because DNA is identical, and it is the unique genetic code from which we each emerge. With twins - DNA is the same, as are the chromosomes, but the proteins, cells and organs which are transcribed/expressed from that DNA may vary slightly.

No. Identical twins are genetical clones but they have absolutely two diffenrent souls, different characters.\nIf God will ever allow people to be cloned, then He will also give these clones souls - because the clones are real people, with real needs, real life - and real soul.

This is really all about genetics. Each person has differing genes and inherit family traits!

Your "soul"?  What are they teaching in biology class these days? :-)\n\nLook, a person and their clone would be no more alike than two normally occuring identical twins.  In fact, genetically, that's exactly what a clone is ... just an identical twin.  They *look* alike, and may have some similar propensities (they may both be naturally talented at math, say) ... but other than that they are two completely independent human beings.  They will have different experiences ... that makes them different.\n\nAs for your "soul", biologists are happy to leave that to the spiritual folks.  Biologists have no opinion either way.

I think that the DNA would be the same as any other human.

No.  The children will be blessed with their own unique set of DNA, although they will probably look like siblings.

LOL...sorry I was just wondering this the other day. I have no idea but I have noticed that. It looks like they could be brother and sister. I guess they just spent all that time together and kinda take in the others looks, ex: hair, expressions, personalities, weight-gain or loss, facial characteristics. Take my brother for example, him and my step dad look exactly alike...curly hair (looks like a afro sometimes...they are white though that's the funny part!), weight gain (both look like twins when you see them from behind, love handles and all ha ha), it's funny how it happens, kinda scary too!

No its impossible. The DNA is completely different, and plus cloning was banned by the Geneva Convention a couple of years ago I believe. But if your like the other groups and you want to try it, have at it. But if you do clone it together, dont tell the press or you might just end up going to prison.

looking for relatives via DNA

Yes, certainly.  We all have the same ancestors: Adam and Eve.

Yes, same family tree.

No.  If, however, you had a set of twins:\n\n(1) Sisters 1 and 2 who are idential twins\n(2) Brothers 1 and 2 who are identical twins\n(3) Sister 1 marries Brother 1\n(4) Sister 2 marries Brother 2\n\nThen: their offspring would be equally well-related to each other.  That is to say, each child from either couple would be equally well-related to their brothers and sisters as they were to their cousins.\n\nThere would be only standard risks of problems with the children and this would NOT have any problems associated with incest that other users appear to believe it would.

Actually, all life shares DNA to some degree. While primates may have less differences than humans, only 5% of DNA is different in each species. The other 95% is shared by all life.

sooo, i only share 50% of my DNA with my dad, whom i actually look like; and you want to tell me that this ape has more in common with me than my dad: whose genes i actually have?  your logic is screwed up.

I'm not sure what exactly you mean? But if you are wanting to know similarities and that it depends on if they are identical or not. Some twins can have everything in common and look a like and some have nothing in common and don't look a like and just because they are identical doesn't mean that they will act alike as well. Twins are born at the same time yes but they are there own person if you get what I'm saying. My mom is a identical twin her and her sister hate each other and have nothing in common except they both lie. Twins also run every generation her her side of the family.

Hi! I'm the mother of identical twins.  There's alot of misinformation out there.  Here's a few facts:\n\n1. Identical twins are from the same fertilized egg that splits so identical twins have identical DNA.  However, this does not mean that they will look exactly alike.  I can tell my identical twins apart easily and even strangers can look closely and notice subtle differences.\n\n2. Fraternal twins are from two seperate eggs that are fertilized at the same time.  They are basically just brothers/sisters who happen to be born at the same time.  You would expect them to look as similiar (or disimiliar) as siblings born years apart.\n\n3. Really, there's no reason why you should hesitate to ask them if they are fraternal or identical.  They'll probably appreciate that you actually know that there are different types of twins and that you didn't assume they were a certain type.\n\nHope this helps!
