How accurate is DNA?

[JLM]

Identical twins recently had their DNA examined for ancestry, which showed quite different results. What do we read into this?

Depending on your level of education you either blame the science or the scientist.

Well you being the only one on here that hasn't finished highschool yet you pick. The opposite will be the coorrect answer.

In fact there's little difference in the numbers.

Hoid went to ancestry.com and found out he's 20% Irish...20% Scottish...and 60% jackass.

Hah! Good one T-Bones...

There was a rumour going around the Capital a few years back that our former Prime Minister Joe Clark was the lovechild of John Diefenbaker and his secretary at the time. Can you see the resemblance?...

The one sister had an ethic group present where it didn't show up in the other sister and vice versa (if that is little difference in numbers) as I understood while watching it.

You didn't understand though

Identical as opposed to fraternal.

I found it fairly easy to follow, I thought, not being total rocket science.

I would question using Ancestry.com as being representative of science.

The Claim: Identical Twins Have Identical DNA. It is a basic tenet of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and, thus, share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not
