Did you do Biology at high school?

It's part of the Genetics part of the Year12 ciriculum (it was when I was in
Y12).

And to make matters worse I can't remember the formulae for the caculations,
but it's something in the order of a 50% chance of the siblings having red
in the first generation, dependant on the amount of coding in the father
(blond hair) for red.

The children of the children would have also a 50% chance too, even if the
the sibling has jet black hair. But their children would have like a 10%
chance assuming no other red genes were introduced into the pool.

I may be wrong here because it's been so very long since I did this stuff,
but it's fascinating from memory.

Fascinating in that blonde hair and blue eyes (The Ayrian look) are actually
recessive genetic characteristics, and some one historic didn't realise this
before they went on a rampage trying to create a "Master Race" - LOL!
