Hello, I did a science project on fingerprints called "Are fingerprint patterns inherited." I got the science project idea on sciencebuddies.com. They give you a lot of information. By the way this project is a 6th-7th grade project. Here is what I put. Materials: Black ink pad, Pencil, white paper, Family members, unfamily members(optional), Printer, Computer, Magnifying glass(optional), wet paper towel. Purpose: The purpose of this experiment is to determine whether or not fingerprint patterns are inherited. Procedure: 1.Take one person's fingerprint. 2.Find out what type of fingerprint that person has. 3.Test their parents fingerprints. 4.See if their parents prints are the same or similar. Hypothesis: I don't think that fingerprint patterns are inherited. It's because I know no two people have the same fingerprints. Conclusion: Opposed to my hypothesis, fingerprint patterns are inherited, but individual ridge features are not. The fingerprints may be similar but not identical. Data: Percent of similar fingerprints 80% to 20% | ||

Level 1 detail is impacted by heredity (may be very similar between family members). Levels 2 and 3 are random and will be very different between family members. In the Fingerprint Sourcebook, see Chapter 3 (and also 2) for detailed information. | ||

Okay so im doing a science fair project on fingerprint Patterns inherited? and im so confused in what the independent variable and the dependent variable will be. PLEASE PLEASE PLEASE HELP!! | ||

This is a common question, and is answered in the Frequently Asked Questions at this website (click on "Are fingerprints inherited...). A few related articles are as follows: Heredity in Fingerprints, G. Shahan, ID News, Vol XX, No. 4, pp. 1, 10-14.The top two files are in PDF format (in the same file) and may take a few minutes to download if you are using a telephone modem. The third article is a normal web page. Your computer should be pre-configured for PDF (Adobe Acrobat) files. If not, you can download Adobe Acrobat for free from here. | ||

Webmaster note: This posting moved a thread where the same query has been asked and answered. [21 Jan 2008] Hi. I'm doing a science fair project on whether fingerprints are more similar between relations or strangers. And I don't know what to put for my research. Help!! | ||

I need some help helping my daugther do her science project on how do fingerprints differ in the same family please any help will be appreciated! thanks | ||

Yes and no! NO: Family members do not have IDENTICAL fingerprints. No finger in the world will ever be exactly like any other finger. However, patterns can sometimes be very similar. For example, you might have all whorl patterns just like your Mother or Father. But each of those whorls are completely different. Talking just about pattern types, there was some research done in the 60's that showed a 50% parent-child resemblance in a specific aspect of the pattern called ridge-count. The distance from the middle of the pattern (core) to the left delta of an impression establishes the rough size of the pattern itself, and is based on events in fetal life when fingerprints form. This early genetic timing event is inherited half from your mother and half from your father. For example, if your father has a total finger ridge count of 100 and your mother's is 80, you will be half-way in between at 90. It's inherited half from one and half from the other. That was the conclusion of Sarah B. Holt in her book "The Genetics of Dermal Ridges". | ||

Are fingerprints more like their parents or other members of their family? | ||

Pleases read the FAQs at onin.com where your question is already answered. | ||

I am doing a science project on similarities in fingerprints of siblings. Any help please..Do family members have similar fingerprints and if so why or why not???? | ||

It is much higher than random. In 1971, I started my career in fingerprints as a clerk in the largest fingerprint repository in the world (at the time) located at 2nd and D Streets, SW in Washington, D.C. With over 200 million cards on file, I was surprised often when I would classify a fingerprint card and find that in a very unusual classification the one or two other cards in file would have the same family name and hometown. This was truly amazing, considering that all the fingerprint cards in the repository would have made 26 stacks as high as the Empire State Building. Occasionally the birth date would be the same, but more often it appeared to be father and son. Of course, even though the classification patterns, ridge counts, tracings, etc., were the same or similar... the unit relationship of the individual ridge endings, bifurcations and dots was completely different between all the prints. Fingerprint classification (Level 1 detail) does NOT involve unique characteristics; only class or group parameters. The classification rules include (in most large filing systems) sex, age, and the presence of scars in the pattern area. Most folks think FP classification has only to do with loops, arches, whorls and ridge counts/tracings between focal points in the patterns. That is NOT accurate and the entire purpose of fingerprint classification in the classical sense was merely to reduce the number of fingerprint cards to be searched to determine if a person already had a "record" under a different name. In crime lab casework, we often identify latent prints small enough to be covered with a pencil eraser. The unique unit relationship of the individual characteristics Level 2 detail is not repeated on the hands of identical twins... or even anywhere on the papillary (friction ridges) skin areas of the same person's hands or feet. --Ed German | ||

My daughter is researching fingerprints and is looking for information on whether or not there are similarities in fingerprints of family members, between members of the same ethnic group and/or the same gender. | ||

do siblings have similar fingerprints |
