Fingerprints are the ridge pattern found on the tips of your fingers, the are unique and hard to replicate. Fingerprints have been used in law enforcement, crime, and forensics for many years, as a reliable form of evidence. But, though it is, for the most part, reliable, there are some problems, there are hundreds of arrests that have been made solely on fingerprint and biometric evidence. This could be a problem, what if your appearance or gender was the same as that person? what if you shared a family tree? Would you be arrested instead?, Well let's take a look at fingerprint science and our own experiment to find out. There are many different types of fingerprints, such as ulnar loop, radial loop, common whirl, peacock eye (or central pocket whorl), arch, tented arch, and accidental. We decided to construct an experiment where we compared different fingerprint patterns and looked at how similar they were to other people that were related to them and or look similar to them. We didn't know anything about this field of study and were curious and-and interested in learning more about it. We started by fingerprinting our test subjects. We fingerprinted all ten of their fingers. Then we compared it to other fingerprints of people who look like them, are related to them, are related to them and look like them, are related and don’t look alike, and don’t look like them and are not related to them. We also tested pairs of different genders and pairs of the same gender. We concluded that relatedness does affect fingerprint pattern similarity, and that appearance does not, gender seems to affect this, to some degree. We learned a lot from this project and we hope you will too.
