Fingerprints: A Family Matter

CSEF · 2007 Mammalian Biology

Emily M. Russell · Good Shepherd School, Pacifica, San Mateo County

Overview

Objectives/Goals My purpose is to determine if members of the same family have any fingerprint characteristics in common. Methods/Materials My methods were first to gather a sampling of family fingerprints on index cards that were identified on the backs of the cards. I sorted the cards by fingerprint pattern without looking at the fingerprint identities. Next, I entered each fingerprint into a table grouped by family noting what type of fingerprint each member had. Finally, I analyzed the data to see if members of the same family had fingerprint characteristics in common. Conclusions/Discussion I discovered that heredity plays a large roll in determining a person's fingerprints. A majority of my sample group had fingerprints that match their parent's.

Summary statement

Does heredity have an effect on fingerprint characteristics?
