I was wondering about sporadic mutations as well whether they would be heritable and what samples from the twins would be tested. Hi Barry, It’s definitely a complicated situation.

I wonder if the changes you talk about will be found in all cells or just in a subset of each twin's cells. If just a subset, then I suppose the differences you describe will need to happen in the sperm DNA the twin contributes to the child in order to be used in a paternity test. Interesting post.

When I first heard of this story, I was kinda annoyed at the writeups because they were all claiming that it's "impossible" to tell the difference between the two twins by genetics, but that's totally not true--there's just no commercial test available yet (as you pointed out).

You make a great point! It's a bizarre case indeed. Hi Simon, Thanks for the comment. You make a great point! It’s a bizarre case indeed.
