Do identical twins have identical fingerprints?

Identical twins are born virtually indistinguishable, mirror images from the same egg. But that's only the half of it. As they age, life leaves separate tracks on each in the forms of scars and more subtle markings. It's the same with their fingerprints, which are very similar but also different on close examination. In addition to the influence of their environment after birth, they are even born with very slightly different prints due to chance occurrences in the womb, such as position, etc. - what scientists cryptically call "random events."
