Its the opposite, parents with blue eyes can only
pass on blue genes. But also everything we learned in school about genetics is a simplification. Theres a whole spectrum of eye color hues.
Generally darker is seems more dominant so a good rule
Is a child is unlikely to have darker features then the parents.
TIL I cheated on my wife when she had… wait a second. /s
That’s not true at all. Blue eyes needs two recessive genes where Brown eyes only need one recessive gene. So you can have parents where both have brown eyes but they both have the dominant gene for brown eyes and the recessive gene for blue eyes. Then if both recessive genes are passed on to a child they will have blue eyes.
Of course there’s a few more complications to this as human eyes aren’t predicated on one gene, but it’s a good enough simplification.
You probably reversed something you learned a long time ago. It’s impossible for two blue eyed parents to have a brown eyed child unless there’s a random mutation, which I guess can happen, but is incredibly rare.
Luke has blue eyes.
It is impossible for a blue eyed person to have anything but two blue eyed parents.Well, I don’t know where I picked up that bit of misinformation. The odds of a blue eyed person having two brown eyed parents is 25%.
Not true, genetics can just do weird shit

Eh, you’re close, just backwards - if both parents have blue eyes, the child is (more-or-less) guaranteed to have blue eyes.

I have blue eyes, and my wife has brown eyes. Our daughter has blue eyes. We also have a son with brown eyes.
Recessive genes work that way.

No, the odds of two heterozygous brown eyed parents having a blue-eyed child is 25%. I don’t think these statements mean the same thing.
