O/T A Question For Someone Who Knows About Probability

[Curious Orange]

Apologies for posting this, but it is a question I'd be interested to hear an answer to. It is an odd tangent to my earlier thread about who you support (don't ask, it's just my train of thought tonight!! ). Please feel free to ignore and drop like a stone down the board as I promise not to bounce it back up again.



Does anyone know the probability of the following happening.

That if two sets of identical twins, one set male, the other female, were to have children, what is the chance that their respective offspring were to be genetically identical?

The odds of both sets of parents producing identical twins are
81,224 - 1 . Each set of identical newborn twins would not be identical to the other .

Very impressive. Not actually the question mind, but very impressive.

Statistically speaking the chances of quarternary marriages (the name for identical twins marrying identical twins) is exactly the same as you being genetically identical to your brother, i.e. 0.

However if both couples did have children they would be full gentic siblings,
