Rarirty of finger and palmar prints

Hello patti, martinj, stalin

There is one paper which i had seen which mentions about rarity of prints they did some statistical study and found the whorl on satrun finger (middle finger) is very whether left and right hand is rare. I think the same paper mentions that the Raja loop is very rare (on left or right hand). Iam not sure how far you all would agree, ofcourse whorls on palmar surface or sole surfaces are also rare. but in reference to loop on palmar surface atleast in india i have found very few raja loops. Iam just suprised. I guess even in europe or asia this loop is rare.

Thanks
Anand

In practice, I see the raja loop frequently when I'm reading hands at bar and bat mitzvahs. It is usually in combination with the loop between the middle and ring plus between ring and little fingers.

Hello Anand,

Most studies revealed that the whorl on the middle finger can be seen in more than 10% of Western populations, and in Asian populations it is even more common.

And far most studies confirm that a whorl on the middle finger is more common than a whorl on the pinky finger. So I don't understand why you call it 'rare'.

PS. I can confirm Patti's comments.

Hello Patti, MartinJ

What is Batmitzvah i refered in the net and it means some judiasim somethingh, anyway what iam understanding form this these people in batmitzvah have this combination of various loops such as raja, ect.. Okay but still when you take world population it is rare, but i also find that whorl on middle left or right in around 5-10 out of 100 samples, if we look randomly then the percetange seems to be small, ofocurse whorl on pinky finger is rare, also whorl on soles (feet) is also rare when compared to population.

I know a person who has all this rare combinations, then do u think that person is unique.

The other thingh is lenngth of mercury finger above first phalange of appollo is also rare based on my sampling study it is around 5-10% out of 150 people.

Thanks

Hello Martinj, Patti

Can we say that an pattern intensity value on fingers of more than 16 or 17 can be said as rare. Similalry can we say that a palmar pattern of more than 6 or 7 loops (Raja, Seriousness, Humor)on the mounts (inclusive of right and left) is rare. In india i have seen people having whorl on either of the mercury finger, ofcourse i need to increase my sample size. I would like to know about toe, bcos there is lot of rarirt on toe prints and there might to be somethingh to it, there is a paper by siemens if iamright who has written a paper on this. I would appreciate your reply

Thanks
Anand

Well, your first question requires two answers:

- For populations: yes, a 'pattern intensity' of 16 or 17 is only rarely seen in specified populations (in far most populations around the world the 'pattern intensity' will result in a value between 9.5 and 16).

- For individuals: no, a pattern intensity of 16 or 17 is not a 'rare' characteristic at all ... because about 20% of all people have 6 or more fingerprints whorls (which is usually resulting in a 'pattern intensity' or 16 or higher).

And your second question can be answered likewise with two answers.

Hello MatrinJ

Okay, i gotcha. But then can i say somethingh about a finger pattern intensity of 18 (8 or more,) can be said to be around 10% people, and a whorl on mercury finger would be rare. Similalrly a palmar loops of around 7 or more would be around 10% of people and people having 8,9 or 10 whorls is rare. Probably 10 is very rare, 9 rare and 8 rare.
also what i personally think is finding total pattern intensity using penrose formula and seeing what is rare in it (this might provide interesting information on rarity), what would be your suggestion.

Thanks for the information.

Hi Anand,

Okay, nice to hear that my examples were usefull for you!! Very Happy

By the way, you haven't described (in terms of a percentage) what you assume to be a characteristic is 'rare'.

From my piont of view, in order to speak about a 'rare' characteristic - I think we should limit that to hand characteristics which are seen in (far) less than 1% of the general general population.

Would that make sense for you as well?

(By the way, I think all characteristics that you've mentioned in your last post, are seen in more than 1% of the population)

PS. In the perspective of fingerprints types, there is only one type which is only 'rarely' seen in any finger: the so-called 'accidentals' (which can be described as a whorl-variant). But regarding the combinations on fingers... MANY combinations are quite rare, for example: 10 arches are seen in only about 0.1% of all people (about 1 in a 1000 person has this combination).

This table provides you an impression about the occurence of the most common types among the 5 fingers (the data are based on the fingerprints of 2000 people):

And maybe, you will enjoy to study the details presented in this article:
http://www.handresearch.com/news/fingerprints-world-map-whorls-loops-arches.htm

(Including links to 13 articles which present data about the frequencies for the occurence of the various fingerprint types among the nations)

NOTICE: Though pinky fingers typically show an 'ulnar loop', about 10% of people has a whorl on at least one of his or her pinky fingers, and about 3% of people has a whorl-related type on all 10 fingers. Therefore, if you agree with me about using the 1%-criterium for recognizing a 'rare' characteristics... this 10% implicates that you better not call it a 'rare' characteristic. Makes sense?
