will the genetic code for identical twins affect their thumb impression?

if the genes coding for the identical twins are same then this may be the cause for the same thumb impression isn't it?

and because of this there may be difficulty in the forensic findings.

and will continue to change as their life progresses also.

police look for tag nodes and terminations to a set pattern to a rough scale, a scar form a cut will alter these also.

twins are not exempt from finger prints :)

and the issue of DNA is also open to debate as well.

You are Unique, be sure! :)

fingerprint is not decided by human genetics, thus, two people with the same gene will not have the same finger print. although the fingerprints of twins will be similar, they are definitely not the same... if nothing happens.

 

who, what and when did someone said this? if they aren't controled by the genome, they by what?

i'm sure you've taken into the account the whole process of meiosis, pleiotropy, polygenic traits, principle of independent assortment, principle of segregation, dominant genes, co-dominant genes, recessive genes, etc.....?

i think that linky adds more confusion as not even those guys seem to have more or less a definitive answer plus they contradict each other on various points ;)

 

but it all comes down to this: you are unique with respect to finger prints, genome, eyes, etc.

So identical twins' DNA are not the same?

 

 

It's just that DNA is not the only determining factor in fingerprints or many other charateristics influenced by the environment.

 

...and technically, no, identical twins do not have exactly the same DNA because of mutatations.
