A Child's Imagination Can Really Sting

So, are the twin children from the separate parents genetically brothers and sisters?

Sounds like they are pretty well covered if one of them needs a kidney someday.

Jeebus, my head hurts. Who's the poor little single kid all alone on the left?

and if the children have children together, is it possible to get a genetic identical to one of the first generation twins? (i am not advocating they try)

This just boggles the mind! :)

The little kid at the left is breaking the symmetry. Abandon him.

No fair. My mom is an identical twin and neither she nor her sister had twins. I always wanted a twin sister.

What would of been even freakier if both women had two sets of boys or girls and genetics had caused all four to look almost exactly alike even if there's a few years between them.

I wonder if their kids will marry each other.

It sounds like they should all have 12 toes or something

I wonder if those boy twins and girl twins are more genetically similar to each other than regular boy/girl fraternal twins...

This is one case where cousin marriage should definitely be discouraged.

I sense some confusion here. All that happened is that Diane and Craig had a set of identical twins. No weird genetics, no inbreeding, nothing. The interesting part is that Diane and Craig each have an identical twin sibling (who just so happen to be married to each other).

I think the two little girls in the picture are either sisters or cousins, not twins.

So it's okay if they marry their cousin, then?

i bet the infidelity rate of twins is off the charts

i kind of wonder if it's slightly more likely for twins to have twin children or something.

Has no one ever heard of Tasmania?

It is all totally normal and fine.
