1 in 1 Million????? I don't think so...

If both parents are bi-ratial 50% white/50% black the odds of having a white child are 25% the odds of having a black child are 25% and the odds of having biracial are 50%..

So, I don't see anyway you get to 1 in 1 million odds out of that.... someone lied to these folks.

They must be using Old Math.

"to 1 in 1 million odds out of that.... someone lied to these folks."

The lottery odds are 1 in 10,000,000 , for example, but really it is 50/50. You either won or you didn't.

There is not a single gene that is either "white" or "black." Racial characteristics are based on a group of genes governing hair and skin color and other external features. So the odds of a child having features of both races are very high. For the same reason, the odds of a child having exclusively the features of one race or another are low.

Here's what they said on Snopes:

Skin colour is believed to be determined by up to seven different genes working together.

If a woman is of mixed race, her eggs will usually contain a mixture of genes coding for both black and white skin.

Similarly, a man of mixed race will have a variety of different genes in his sperm. When these eggs and sperm come together, they will create a baby of mixed race.

But, very occasionally, the egg or sperm might contain genes coding for one skin colour. If both the egg and sperm contain all white genes, the baby will be white. And if both contain just the versions necessary for black skin, the baby will be black.

For a mixed-race couple, the odds of either of these scenarios is around 100 to one. But both scenarios can occur at the same time if the woman conceives non-identical twins, another 100 to one chance.

This involves two eggs being fertilised by two sperm at the same time, which also has odds of around 100 to one.

If a sperm containing all-white genes fuses with a similar egg and a sperm coding for purely black skin fuses with a similar egg, two babies of dramatically different colours will be born.

The odds of this happening are 100 x 100 x 100 — a million to one.
