Fingerprint Geometric Analysis
Ridge
Dissociation
Figure
"H" displays a rare and severe degree of ridge dissociation in which
all ten digits are affected. It can be
noted that the entire set of fingerprints display an extreme narrowing of
ridges in the center of the pattern area.
The ridge events mostly encountered in various but somewhat uniform
sequencing are ridge dots, enclosures and bifurcations. Many of the bifurcations recurve in an
unconventional manner with appendages between the shoulders that extend to form
other recurves. In some cases there is
also the rare event of crossing ridges that resemble the configuration of
chromosomes. 
Figure "H" displays this event in a
vertical formation.
Researchers
have discovered ridge dissociation to occur in some individuals suffering from
schizophrenia as well as physical conditions such as epilepsy, down syndrome
and albinism.
