Procedure

Finger patterns exhibit racial variation as shown in the table below:

It is evident from table that whorls are most frequent among the Mongoloid population and least among the Caucasoid population. On the other hand, loops appear most frequently among the Caucasoid groups, while among the Mongoloid and Negroid groups loops are found in equal frequencies. Again arches appear in very small number in the Mongoloid. It is most frequent in the Negroid. The position of the Caucasoid is intermediate.

Usually three indicates are calculated on the basis of the frequency distribution of the different finger patterns. These are as follow:

• Furuhata’s Index=Whorls x 100/loops
• Dankmeijer’s Index=Arches x 100/Whorls
• Pattern Intensity Index=2 x Whorls + Loops/n

Preocedure to be followed:

1. Stay on the images and count the amount of whorls, loops & arches.
2. Enter the amount into the boxes
3. Write the type into the last box.
4. Submit.
