Fingerprint pattern & ridge count distributions among the ABO & Rh blood types, and among the two sexes.

Fingerprint patterns differences were significant for the ABO blood types, with the AB blood type scoring the highest Arch frequencies, and the B blood type individuals scoring higher Whorl & lower Loop frequencies. Rh blood types showed little differences for both variables. Pattern differences between the sexes were minimal. Males scored higher ridge counts on all 3 variables. a Arch. b Loop. c Whorl. d Degrees of Freedom. e Significance.
