Racketoid loops, a.k.a. raketoid loop / racket loop
To all fingerprint experts in the world:
Can anybody give me a description for a so-called raketoid loop? (a.k.a. racketoid loop / racket loop)
PS. The significance of this fingerprint pattern has been mentioned quite a few times in studies presented by Ana Ţarcă from Moldavia (Romania), see for example:

Raketoid
Few years ago, I sent a question to that effect to the scientist but never received a reply. It was my understanding that a raketoid loop was in fact in composite loop.

Racquetoid
Birbeck granules are racketoid in nature. This might help you.

Re: Racketoid loops, a.k.a. raketoid loop / racket loop
Hello cpb, thank you very much for your report!

Yes, I can understand your association regarding 'composite loops' because I have been considering myself that the term 'racket loop' might refer to a specific form of a composite loop, most likely the central pocket loop (a.k.a. peacock)... especially since the central pocket loop is usually most common on the ring finger, which could fit with Tarca's observation that the 'racket loop' is reported to be most common in the 4th or 5th digit.
By the way, I think it is unlikely that Tarca is referring to 'double loops' (a.k.a. twin loops, which are also recognized to represent a specific form of.composites), because double loops are typically found on the 1st digit, where the percentage can easily rise above 10%.
However... I just became aware that Tarca reports for her control group a percentage of 27.5% whorls (which is a bit low, but not unusual at all), however, the percentage for composite patterns (twin loops + lateral pockets + central pockets) is unusually low: only 0,2%... and in this perspective it all would make sense if Tarca's 'racket loop' actually refers to a central pocket, because that would probably implicate that the 0.2% might merely include double loops, see table 1 in her diabetes type 1 study: http://www.jmpiasi.ro/2005/13(1-2)/6.pdf


PS. Meanwhile I have found confirming evidence that Tarca is indeed referring to a 'racket' shape of loop, because in one of her articles she speaks in French language of 'boucles du type raquette' (= loops of the racket type), see page:

I never heard of a racketoid loop before but from the name, which reminds me of tennis racquet (or racket), I wondered if it is a peacock's eye.?

Yes Lynn, likely a peacock (see my previous post); my problem raised from Tarca's description for her 'racket loop'... which she describes to be very rare in the normal population.
However, we know that peacocks are not rare at all... and therefore I now think that my problem likely resulted from the fact that Tarca's dissertation study from 1995 presents a control population involving 200 people from Romania (100 males + 100 females) where coincidently the prevalence of 'complex' patterns (including twin loops, lateral pockets & peacocks) is reported to be very low: 0.2%... while Cummins & Midlo report a percentage of 5.2% for the same patterns based on Scotland Yard data involving 5000 individuals.
PS. Curiously, the prevalence of whorls is not very low in Tarca's controls: just below 30%, versus 25,4% in the Scotland Yard data... which actually does perfectly make sense in the perspective of the fingerprints world map.

hi Martijn, I did not see your post before I posted, I was looking up cbp's birbeck granules which confirmed tennis racquet shape.
I haven't read Tarca's study yet.
cbp - was it Tarca that you wrote to?

No, I have not contacted Tarca - though I tried, but was not able to track down her contact details.

Re: Racketoid loops, a.k.a. raketoid loop / racket loop
thanks Martijn, but my question "cbp - was it Tarca that you wrote to?"
was directed to member cpb, (SORRY I wrote cbp instead of cpb!) reference 'the scientist' in this post -
