ramanan Posted December 19, 2003 Share Posted December 19, 2003 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.

Quantum Defect Posted February 23, 2004 Share Posted February 23, 2004 No. The fingerprints could be similar, but not identical since they are surface tissue... Link to comment Share on other sites More sharing options...

YT2095 Posted February 23, 2004 Share Posted February 23, 2004 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.

hyperdimension Posted April 7, 2004 Share Posted April 7, 2004 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.

Radical Edward Posted April 21, 2004 Share Posted April 21, 2004 if they were the same, then this would imply that there is a genetic map for practically every cell in the body. This is not true, and the particular fingerprint patterns will be the result of small perturbations, most noticeably during development. Link to comment Share on other sites More sharing options...
admiral_ju00 Posted April 30, 2004 Share Posted April 30, 2004 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.....?

booper54 Posted May 2, 2004 Share Posted May 2, 2004 So identical twins' DNA are not the same? Link to comment Share on other sites More sharing options...
Ms. DNA Posted May 2, 2004 Share Posted May 2, 2004 To get back to fingerprints and genetics, I searched on Google and found this link, which explains how fingerprints form. http://www.newscientist.com/lastword/article.jsp?id=lw474 Link to comment Share on other sites More sharing options...
admiral_ju00 Posted May 2, 2004 Share Posted May 2, 2004 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. Link to comment Share on other sites More sharing options...
fafalone Posted May 2, 2004 Share Posted May 2, 2004 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.
