Can a grey eyed mother and a blue eyed father have a brown eyed son?

What color are tthe mailman’s eyes?

Apparently it is, as my parents were blue eyed and grey eyed and I am a brown eyed child.
I have always questioned this myself. And my eyes are very dark brown, not a light brown.

Sure. Eye color is a polygenic phenomenon, and brown might show up somewhere in anyone’s genotype. Ancestry goes back a long way.

Yes, it’s possible.

I think brown is dominant, so yes….not sure about a blue eyed kid with brown eyed parents, though…. (grey eyes?)

Yes, provided both have recessive genes for brown eyes.

Genetics are very interesting.You already know that the answer is yes.

@galileogirl That was really wild!—The minute I read the question, I immediately clicked on it to answer: “What color were the mailman’s eyes?” And there was your answer, staring at me…the exact words. It was a momentary kind of “reverse deja vu” thing. heh heh heh.
This is too much of a coincidence, we must be meant for each other. It is fate. BTW, what sign are you? LOL

@dpworkin- Not true. Blue plus blue always equals blue (or variants of; green, hazel, gray…, but never brown).
Blue eyes are recessive. Therefore if the father has blue eyes and if the gray eyes on the mother are really bluish-gray there can be no brown-eyed child from that coupling because neither parent carries the gene for brown eyes. Brown is dominant so if the gray eyes are actually brownish-gray then it certainly would be possible.

@galileogirl- They’re blue.

Quoting Professor Moran: “One of the most puzzling aspects of eye color genetics is accounting for the birth of brown-eyed children to blue-eyed parents. This is a real phenomenon and not just a case of mistaken fatherhood. Based on the simple two-factor model, we can guess that the parents in this case are probably bbGg with a shift toward the lighter side of a light hazel eye color. The child is bbGG where the presence of two G alleles will confer a brown eye color under some circumstances.”

Was this a Dolly Parton track?

It’s possible.
