Abstract:
The work presented in this paper has two main objectives. The first objective was to determine if fully related siblings have similar fingerprints due to genetics. The data showed that only one sibling set had less than 40% similarity. The right index finger of all sets had a median of 40%, even within one set of siblings that had only a 20% match on the right thumb. The mode for the left index fingers was 40% with twelve of the fifteen sibling sets being at that level. The majority of the sets were at 33% or higher, yet two sets had no matching major classifications and the mode for ridge classifications was 80%. Arches were the least found major classification and loops were the most popular major classification. The hypothesis was that fully related siblings would have similar fingerprints. The results support the hypothesis even though the fingerprints may have slight differences within some classifications, all sibling sets having at least an 80% similarity. The second objective was to determine if fully related siblings have similar toeprints. The data from toeprint collections showed that most of the sibling sets ridge classifications being 80% similar and three of them 90% similar. While the similarity of the ridge classifications did not vary much, the similarity of the major classifications varied.
