Identical twins (同卵双胞胎) may not be exact copies at the DNA level after all. Normally, identical twins differ by 5. 2 genetic changes. Researchers shared their new finding in Nature Genetics.Identical twins are also called monozygotic twins (单卵双胞胎). They come from a single egg. ...
As identical twins, they found it easy to confuse people.But an appellate court has rejected the implication that that's behind a bizarre child-support dispute in Illinois, one that has pitted the brothers against each other and has rendered DNA technology useless.The Fourth District Appellate ...

Identical twins form from the same egg and get the same genetic material from their parents — but that doesn't mean they're genetically identical by the time they're born.
The tests showed that the two shared identical DNA profiles, with 23 allelic loci tested showing 100 per cent perfect match which is consistent with the Sharon and Melon being biologically identical twins. Ms Rosemary Khaveleli Onyango could not be excluded as the biological mother of the twins...
At present, the takeaway from this new study is that scientists should not assume that identical twins are sharing 100-percent the same identical DNA. Such assumptions could lead scientists to overestimate the influence of the environment, when actually, a genetic mutation may be the source of ...
