Ulnar trend of bifurcations on finger tips?

Hi,

apologies if this is an obvious question but do biffrcations on tips generally have an ulnar trend (e.g. 'open out' towards the little finger side of the hand)? Or do they just tend to open out to whichever side a delta may be on?
Any thoughts or links to research would be greatly appreciated.

They typically point in the direction of the hand they are on....

Of course there are always exceptions but that would be the first place you would wanna look.

Hi Dan

I did a lecture for the Fingerprint society on this. It was based on Ron Smith's
Dominant Deltas. If you want to email me at robert.doak@humberside.pnn.police.uk
I will email you a copy of the article that went into fingerprint whorld.
