No, everyones' fingerprints are different. http://www.hhmi.org/cgi-bin/askascientist/highlight.pl?kw=&file=answers%2Fgenetics%2Fans_018.html
DNA is a separate story. Identical twins..the same; fraternal...different. http://ask.yahoo.com/ask/20010213.html

NO. Identical -- or monozygotic -- twins form when a single fertilized egg splits in two after conception. Because they form from a single zygote, the two individuals will have the same genetic makeup. Their DNA is virtually indistinguishable.
However, fingerprints are not an entirely genetic characteristic. Scientists love to use this topic as an example of the old "nature vs. nurture" debate. Fingerprinting, along with other physical characteristics, is an example of a phenotype -- meaning that it is determined by the interaction of an indivdual's genes and the developmental environment in the uterus.
The 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.
Thus, you will find similar partterns of whorls and ridges in the fingerprints of identical twins. But there will also be differences -- just as there are differences between the fingers on any individual's hands.

No, they do not. Finger prints are unique to the individual.
DNA? I guess your quesiton about that is "if identical twins are identical and their genomes are expressed similarly, why arne't the fingerprints the same". Well, even in identical twins, you are going to have differences. A good genetics class can spread some light on that one. There in lies the difference that creates different finger prints per person.

Yes, Identical twins have the save DNA, and therefore also the same fingerprints because your DNA codes for the epithelial ridges.

No, everybody has different fingerprints no matter how similar they look.
I am not sure about the DNA one, I think identical twins and family members have similar dna but not identical.

No. Nobody in the entire would will ever have the same fingerprints. Some strands of the DNA will be the same, but not all of them.

The fingerprints are different and the dna is the same.

They have the same DNA because they come from the same egg, but the swirls on their fingertips form as they move in the womb so they will be different always.

no, identical twins do not have the same fingerprints... but the do have the same DNA

ofcourse not..finger prints don't even depend on the DNA.. it's just the way the baby was positioned in his mother's uterus during which his skin was forming determines the shape for a baby's or person's finger prints..
