Ok, today I posted a thing that was like +17 and right now downvoted to hell.

Just a couple of histories and an honest proposition of sharing my knowledge about a subject a really studied in deep back in the day.

The thing is there are some indicators that can tell you a child is not his father's and they are so obvious! At least with a 99'99% of security if that's the case.

Having a mulato being both white is the most common one. But there are some more like colour of the eyes as accurate as that one.

So... It's objective, I can answer those questions and well. Guess some troll was really pissed with the answers.

So, open to questions.

For example: both parents blue eyed can have a brown eyed kid? No

Both parents with brown eyes can have a blue eyed kid? Yes, depending on their grandparents and beyond, but with a 25% chance if all the rest is favorable

Can a father blood type A have a kid with blood type AB with a mother that is also A? No way

If both are blood type A they can have a zero type kid? Yes, actually that's 25% if conditions are there + 4% of a thing called genotype Bombay...

And so on..
