do identical twins (therefore clones) have identical fingerprints? they are a genetic thing, not influenced by enviroment so i always assume they did, but now ive had doubts raised.

No, twins do not have the same fingerprints. Therfore clones would not either.

why? isn't it a dna thing? or are they forged during growth and birth?

You know how your fingers look if you stay in the bath for a long time (all wrinkly). Now imagine that going on for 9 months.

They would, however during formation they get pushed and shoved and the 'prints alter slightly.

There are some schools of thought that say that a clone will somewhat different from the person being cloned because it develops in a different physical and biochemical environment.

I personaly don't subscribe to this theory, but it does have it's merits.
