Do Twins have the same DNA>?and Finger prints? What are the ways to tell them apart medically?

[waheed]

No

[waheed]

Ive always heard "no two people have the same finger prints, not even identical twins"

Guess the same goes for DNA

[canadateck]

I agree But thre is a % in DNA and finderprints that someone might have the same.

[canadateck]

No

I agree but have heard so many storys,not sure what is true.

[waheed]

Dont know much on the topic, but DNA does consist of a very complex structure of information that one tea spoon of DNA has more information than a library.

OK, did a quick google, its possible twins can have same DNA, but NOT same finger prints.

[Noahtuck]

Yep, i was just gonna say, i saw twin brothers on tv once and they both slept with the one brothers GF but because she was actually HIS gf, they stuck him because even with dna test's they could not prove who was actually the father.

Monozygotic Twins (identical) have the EXACT SAME DNA, but slightly different fingerprints.
This is due to the fact that fingerprints are not entirely genetic; they are partly genetic, but partly formed in the womb AFTER their DNA codes have been determined.

BTW: I am an identical twin.

[bigmicka]

hasnt recent research indicated that DNA is not a solid structure and that over time we add information to our DNA sequence, making it more fluid and changable?

so out of the womb and for the first few months the DNA will be the same, but over time with exposure to different things the DNA will change slightly.

Whether that is enough for testing to prove which twin is the father im not sure.

Fraternal twins (two eggs released at the same time in the womans womb fertilized by two separate sperm) have different DNA, the same as normal brothers and sisters do.

Identical twins (one egg fertilized by one sperm which then splits into two cells completely) have identical DNA throughout their lives. These twins will look identical most times except for really minor differences which their upbringing or lifestyle influences. I assume it's this type you're talking about.

Just as you'd have a hard time telling twins faces apart, the same degree of difficulty would be present in telling their fingerprints apart. With some twins you have to look very carefully to see any difference and with others it's quite obvious.

I knew a set of twins where one brother started smoking a few years before the other. By the end of high school one twin was a full one and a half inches shorter than the other twin. This difference was even reflected in their faces as one's features were slightly more 'compact' than his brothers. (Still exactly the same DNA)

I knew another set of twins that no matter how much you looked at them you couldn't spot the difference. Nobody could. No matter how clear an image in your head you got, you still had to account for the normal day-to-day changes that all people go through. In the end, one got an ear piercing just so people could tell the difference.

So having the same DNA doesn't make a person a carbon copy of it's twin. What they're exposed to in their individual lives plays a major factor. (eg. exercise, diet, diseases they've been exposed to, etc.)

But, since identical twins have the same DNA it's impossible to determine paternity or even maternity in some cases. For instance, if a set of twin boys married a set of twin girls, their children, instead of being cousins, would be brothers and sisters by scientific standards. If you had the batch of children at the hospital all at the same time, you wouldn't know which of the mothers each child belong to nor which of the fathers, and there would be no test able to tell since both mothers have identical DNA and both fathers have identical DNA.

Hope that clears that up for ya.

lets say one monozygotic twin had sex with the same woman & she got preggers.. the twin who had sex with her denied it was him, instead saying it was his brother.. and the woman wanted child support.. how would the court determine who had to pay?

[Shadowmistress]

Scientifically, they can't. They'd have to go on testimony.

[vitualis]

Monozygotic twins have essentially identical somatic DNA... which is generally what counts.

There are differences in the the activation/deactivation of some genes, differences in the distribution of mitochrondrial DNA and obvious, cells will highly variable DNA will be different too (e.g., in gametes and immunological cells).

Whoa! I don't know if I'd be comfortable sleeping with my Brother's sister-in-law!

[Shadowmistress]

Your brother's sister-in-law would be your wife. :P

Can someone give me a straight answer?

I don't think any one here can give a complete answer because no one here really knows, unless someone here is Doctor specializing in that area, and none of us have enough of a understanding to be able to conceptualize, let alone know the meaning of the severe jargon required to speak accurately about the subject.

Just take a look at vitualis' last post...how many of those technically specific words could you identify by sight or use properly if you were debating with an expert in the field?

Better? :P
