VARIATION IN FINGERPRINT PATTERNS ASSOCIATED WITH FAMILIES: A CASE STUDY OF NORTHERN CROSS RIVER STATE
Abstract
Fingerprint is very unique even in identical twins, they are used for security checks and control,
crime scene investigations etc. Fingerprints are phenotypic genetic traits that people are born
with, which are formed at the end of their fingers, fingerprints varies from individuals in their
valleys and ridges The specific aim of this research was to determine the variation in fingerprint
patterns amongst family members. Plain paper, laptop etc, are used. Right thumbprint patterns
and ridge density counts between families in Northern Cross River State were documentated.
The samples for the study includes 100 subjects and they were randomly selected between the
age of 18-45 years. The subjects were asked to clean their hands with wipes to remove dirt and
grease. Their right thumbs were stained with ink and pressed in a plain paper. The results of this
study showed that Northern Cross River State has the highest number of loop pattern (55%),
followed by whorl (39%) and arch which has the least pattern (6%). Male has (35=loop,
26=whorl and arch=4) which has the total number of 65. Female ( 21=loop, 15=whorl and arch
=2). The present study will be of of great importance in forensic Science reviewing the
uniqueness and hereditary in fingerprint of some families in Northern Cross River State.
