Genetics Science Fair Project

Fingerprint Patterns: Who Has the Most Influence?

Fingerprint Patterns: Who Has the Most Influence? | Science Fair Projects | STEM Projects
Ever wonder why your fingerprints look the way they do? In this project, you'll find out if it's your mom or dad who has the most influence on your fingerprint patterns.


The hypothesis is that the male parent affects the offspring's fingerprints more than the female parent.

Method & Materials

You will spread ink on a plexiglas slab, roll your fingers in the ink, and then roll them on a card. You will then study each print and label it with a pattern type.
You will need ink, a roller, a plexiglas slab, and a card.


The results of the experiment showed that the male parent affects the fingerprints of the offspring more than the female parent. However, further testing is needed to determine if there is a tendency toward fingerprint dominance by one sex or the other.

Why do this project?

This science project is interesting because it helps us understand why our fingerprints look the way they do.

Also Consider

Experiment variations to consider include testing different family members, such as grandparents, aunts, and uncles, or testing different age groups.
