Do identical twins have identical fingerprints?

Your fingerprints are different from those of everyone else on Earth. The whorls and ridges on your fingertips are determined partly by your genetic makeup. But if you had an identical twin with the same genetic makeup as you, would your fingerprints still be unique? 

Identical twins, also known as monozygotic twins, come from a single embryo that divides in two early on in development. The result is two individuals that share almost the same genetic information from each parent and look almost exactly the same. Identical twins are essentially clones of one another, although genetic mutations in the womb mean they don’t quite share 100% of the same DNA, Live Science previously reported.
