Let Your Fingers Do the Talking

CSEF · 2018 Mammalian Biology

Clara L. Cady-Dreher · Rio Del Mar Elemetary School, Aptos, Santa Cruz County

Overview

Objectives/Goals The objective of this study is to determine if children carry the same fingerprint patterns as their biological parents. Methods/Materials Standard FBI issued 10-print fingerprint cards, black fingerprint ink (both of which are used by law enforcement for clarity and consistency) and a lighted jeweler's loupe. Results Several families with varying numbers of children were fingerprinted on standard FBI fingerprint cards with black ink. Fingerprints were classified into one of the 3 basic fingerprint pattern categories. Each fingerprint of each family member was further classed down into the 3 basic fingerprint pattern sub-categories. Each family member was compared with one another to find similarities and differences. Conclusions/Discussion Several families were fingerprinted and compared and the results were consistent that no child carried a fingerprint pattern that one or both of their biological parents did not carry. Furthermore, when compared at the subcategory level, the results remained the same.

Summary statement

I found that children carry fingerprint patterns that one or both of their parents have.

Help received

I conducted the fingerprinting of families myself. However, retired Evidence Technician and court qualified Latent Print Examiner reviewed my classifications to ensure they were correct.
