A good friend of mine, who lives across the cul-de-sac from me, has 5 children, and all of them are redheads...but the mom has naturally dark brown hair, and the dad has naturally light blond hair...all 5 children are theirs, biologically, and all 5 have very bright red hair...
People who dont know this couple, often make the wrong assumption, that their children are all adopted...this is untrue...none are adopted, they all belong biologically to this couple..I had thought that at least one of children, would have favored either the mom or the dad, but none of them do...all these children greatly resemble each other, not just in hair color, but in their facial features...in fact the two older girls, just a year apart in age, look like identical twins...the 5 children look as tho they all belong in the same family, but not with the mom and dad that they have...
Its really kind of weird...
One of the more interesting traits I recently learned about is that redheads need more anesthetic and pain relief (for surgeries, dental work, etc.) than non-redheads! Who would have known? No wonder it took my then-6-yr-old so long to come out of his anesthesia after an MRI.
