RESUMO
To determine the distribution of finger print among students of Ziauddin University belonging to different ethnic origins specifically pertaining to different ABO blood groups and also to correlate any relation between fingerprint pattern with ethnicity and ABO blood groups. Cross sectional study. This study was conducted at Ziauddin University Karachi from 1st Jan. 2010 to 30th June, 2010. This comparative study was carried out at Ziauddin University Karachi. 250 students, 50 students each from 1st year to 5th year were included by simple random technique.

Also students with permanent scars on their fingers and thumbs and deformities on finger either due to acquire or congenital traumas were also excluded. Fingers prints of both hands including thumbs were taken on a plain paper with a stamp pad by plain method. ABO Blood grouping of each student was performed. A Performa was made in which name, age, gender, ethnicity, type of blood group and type of finger print pattern were tabulated. 138 students were males and 112 were females with ratio of 1:2:1. Age range was between 19-24 years. Loop pattern were predominant [48.8%], followed by whorl pattern [32%] and then arch [19.2%]. Blood group B was most frequent [47%], followed by O group [27%], A group [18.8%] and AB Group [6.8%] respectively. Applying chi square test the p value obtained in variables i.e. finger prints with blood groups and fingerprints with ethnicity, no significant correlation was found. No significant association was found in types of finger prints with ABO blood groups and type of ethnic origin respectively. This study requires to be done at larger scale with larger sample size representing true indicator of population
