Identical Twins and Recognition.

Human Face >> Science >> Biology >> Genetics








Identical Twins are not clones but result of single fertilized egg splitting into two separate embryos. In scientific terms it is referred as monozygomatic. 

It becomes very difficult to identify subtle differences that differentiates mirror like individual. If you really want to stress your identification skills then you must visit Twins Days Festival in Twinsburg, Ohio. 
Facial variation in genetically identical twins can be exaggerated by engaging them in separate environmental conditions.


A famous book Identical: Portraits of Twins By Martin Schoeller (Author) 

Curious mind raises many questions such as, Can Biometrcs ID an Identical Twin?
But it is found that sometimes many twin faces confound various Facial Recognition software. The best performing algorithm has 17-18 percent equal error rate which should be  under 5 percent. Still, Scientists are studying relentlessly to solve this riddle. One of the paper is "Analysis of Facial Features in Identical Twins" by Brendan Klare, Alessandra A. Paulino, and Anil K. Jain. 
Although, Close friends and even Mom and Dad can be duped by their identical twins, But interesting fact is they can't dupe dogs? and they also have different fingerprints. Also, as identical twins get older, generally more differences in physical characteristics develop.
