Mother nature is merciless. Reading around I just remembered one thing I watched in photographs not so long ago. About a family.

The parents both had blue eyes. Well... One of their kids has brown eyes. That is not possible. I asked if he was adopted to the girl showing me them (none of them where present).

  • Why you say that?
  • Genetics
  • That's nonsense. It's his
  • ....

Well, it's not. For sure. I'm 99,999999999999% sure about it. Science bit...

I'm not analizing genetic parameters all the time, but there are a few so easy to spot!

Like color of skin and race. No half-asian or mulatos from white couples. The colour of the eyes. The type of blood: no A's or B's appearing from nowhere (unless fenotype Bombay which is extremely rare).

And some not that obvious: the way hair implants on the forehead. Ears are sticked in head. The shape of the nails.

And even some more rare like diseases.

It's not always direct or intuitive (direct bragging, I got an A+ in college on that subject, STEM and it was not an easy one...). Anyway... If you understand genetic rules you can spot those without even need of genetic test.

And yes, is not the first time. Other time I remembered was a friend of mine, he was adopted and open about it. He told me but I already knew it. And I can recall that happening again, a "couple" doing queue in McDonalds. One of the kids wasn't his for sure

Anyway open to questions regarding that.
