No, the thumbprints on the left and right
hand are not identical. Even if they are the
same type of finger print (loop, arch, or whorl)
and they look the same, they are not exactly the
same. Fingerprints are partially genetically
determined, and partially determined as a fetus
develops, although the exact mechanism for
fingerprint formation is not completely
understood. If fingerprints were completely
determined by genetics, the left and right
thumbprints might be identical, but because
other factors are involved, every fingerprint
turns out differently. The complex formation of
fingerprints means that even identical twins
have different fingerprints.
