![]() One such study investigated fingerprints in identical twins by looking at samples of their prints from different angles. ![]() Some studies, however, have touched on the misconception that identical twins have the same fingerprints. In fact, the National Forensic Science Technology Center states that, “no two people have ever been found to have the same fingerprints - including identical twins.”Īlso, it’s important to keep in mind that fingerprints also vary between your own fingers - this means you have a unique print on each finger. But having such similarities to the naked eye doesn’t mean the fingerprint composition is exactly the same. While anecdotal articles online often discuss the possibility of a chance that the science could be wrong, no research has found that identical twins can have the same fingerprints.Īccording to the Washington State Twin Registry, identical twins may share similar characteristics of their fingerprints, including the loops and ridges. The chances of identical fingerprints in identical twins is slim-to-none. What are the chances of identical fingerprints in twins? That’s because the formation of fingerprints is dependent on both genetic and environmental factors in the womb. Some underlying differences can include weight and height.įingerprints aren’t included in these genetic similarities. In fact, it’s said that one in four identical twins mirror each other.Įnvironmental factors can still create slight differences in identical twins’ physical appearances, though, which is how other people can essentially tell them apart. They share many physical similarities as a result of shared DNA, including hair color, eye color, and skin tone. In fact, according to Smithsonian magazine, a 2021 study of 381 identical twins and 2 sets of identical triplets found that only 38 had identical genes. Identical twins, on the other hand, form within the same egg that splits into two, which results in the two individuals having similar, though not exactly the same DNA. This isn’t possible in an identical set of twins. Since they share no more DNA than siblings that aren’t twins, it’s possible to have one boy and one girl in a fraternal set of twins. Fraternal twinsįraternal twins develop from two separate eggs and two different sperm.Īccording to the Minnesota Center for Twin and Family Research, fraternal twins share 50 percent of the DNA as a result. The differences ultimately lie in their genetic makeup, or DNA. There are two types of twins: fraternal and identical.
