They don't.
Fingerprints aren't determined by genetics, but by growth conditions in the womb.
(some say it's the amniotic sac, some say it's the inside of the uterus)
Either way, it's different enough even for twins for their fingerprints to end up personal and not shared.
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.
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 patterns 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.

Can fingerprints be a gene?
No, because identical twins which share identical genes have distinct fingerprints.
Do twins have different fingerprints?
Yes. Two people cannot have the same fingerprints. Not even identical twins have exactly matched fingerprints. <3
Is the DNA from identical twins identical What about fingerprints?
There are differences in both DNA and fingerprints.The Claim: Identical Twins Have Identical DNA
Do siblings have same fingerprint?
Identical twins don't have the same fingerprints. Fingerprints are unique to every person, even twins!
How do people get fingerprints?
Every person has a unique (except for identical twins) genetic code that defines what their fingerprints will be. We are born with them.

If you have twin and both come out conected do they share the same fingerprints and why?
Conjoined, "Siamese", twins are by definition identical twins. Their fingerprints will be very similar but often not completely identical.
Do twins have the same DNA?
identical twins do. just not the same fingerprints.
What would distinguish even an identical twin from its sibling?
Fingerprints are different in identical twins.

If identical twins marry identical twins could at least some of their kids look like twins having similar fingerprints?
They may look alike, but they will never have the same fingerprints, because fingerprints are created by differences of thickness in the dermal layer. It is independent of genetics, therefore, twins will never have identical fingerprints and any similarities between twins fingerprints would merely be coincidental.
Do siblings have similar fingerprints?
Depends. If they are twins (Identical) then yes. There has been reports of Identical Twins having same DNA and Finger prints. There has never been any records of regular siblings sharing the same fingerprints
Why do only half of a child's fingerprints match his mothers?
None of a child's fingerprints will match his or her mother's fingerprints. Each individual has different fingerprints. Even identical twins have different fingerprints.
Why dont identical twins have the same fingerprints?
Fingerprints aren't determined by genetics, but by growth conditions in the womb. (some say it's the amniotic sac, some say it's the inside of the uterus) Either way, it's different enough even for twins for their fingerprints to end up personal, and not shared.
