jameswade1977 Posted September 13, 2009 Share Posted September 13, 2009 Some say that identical twins have the EXACT same DNA, a mirror image of each other, others say that every single strand of DNA that develops has what they call a 'buffer' or 'filler' which completes the structural integrity of the strand which makes identical twins 99.999% identical. Do identical twins have the exact same mirror image dna? Link to comment Share on other sites More sharing options...
Darby Posted September 14, 2009 Share Posted September 14, 2009 james, Yes, identical twins share the exact same DNA. If you conduct DNA genotype matching you cannot differentiate between the twins. The differences come in how the DNA phenotypes form the specific structures in their bodies. There are differences - like fingerprints. Link to comment Share on other sites More sharing options...
jameswade1977 Posted September 15, 2009 Author Share Posted September 15, 2009 Thx darby, lets say that jill and jane are identical twins, and, bill and bob are identical twins. Jane has a child with bill named steve, and jill has a child with bob named chris, would steve and chris have the same dna?? Link to comment Share on other sites More sharing options...

That assumes that both sets of twins are incurred no mutation of their chromosomes during their lives. Other than that the cousins would share the same DNA as if one set of the parents had another set of identical twins. Link to comment Share on other sites More sharing options...
