Could someone explain to this non-geneticist why identical twins - who
share the same DNA and genetic patterns - would have different

It is my understanding that identical twins will have similar, but not
identical, fingerprints.  How could this be?  Are fingerprints not
genetically determined? If they are not, what determines the
particular pattern?  Environmental influences?

Please respond via e-mail and thanks in advance!
