Evaluation of the relationship between fingerprints and blood groups in Yemen population

Abstract EN

Background : Fingerprints (dactylograph) is considered as the best tool of identification and usually encountered at crime scene site.

The analysis of fingerprints patterns and blood groups can reveal very important clues which can be used as forensic evidence in crime scene investigation.

Objective : This study is an attempt to study the distribution of fingerprints among the subjects having different ABO and Rh blood groups and to find any relation between them.

Methodology : Of our sample, 2500 Yemeni citizens (1211 males and 1289 females) with different blood groups, ranging in age from 18-32 years.

Results : The majority of these subjects was of blood group O (47.2%), followed by blood group A, B, and AB respectively.

(96.2%) of them was Rh positive factors.

According to our distribution of fingerprints patterns, the loop showed a high frequency (56.8%), followed by whorl, arches and compound respectively.

The blood group O showed more loop (68.7%), while blood group A showed more whorl (65.8%).

Females were more to have loop prints (61.9%), while males were more to have whorl prints (51.4%).

Conclusion : We concluded that the most prevalent digital patterns were the loop and that there was a significant statistical relation between fingerprints patterns and blood groups, on one hand, and the gender on the other hand.
