Both of my grandfathers had blue eyes. I do not. So who has the common ancestor?

Maybe mom’s “joke” that Gypsies stole her real kid from the maternity ward really isn’t one.

There was a lady who worked at the Revco drug store.
She had amber eyes, exactly like a lion.
They were incredible.

Six out of my eight kids were born with bright blue eyes but they didn’t stay that way.

That's interesting. My father had blue eyes. According to my parents, I had them too--or seemed to have them--until they turned green.

“My father had blue eyes. According to my parents, I had them too—or seemed to have them—until they turned green.”

Through most of my life, all my records indicated blue eyes, until the time I was fitted for contact lenses. (Aged 77).

She: “Slide them over until you’ve covered the green”.

Me: “What? Green?”

“So, how did some of the Mandan tribe of North Dakota have blue eyes according to the letters of George Catlin?”

Possibly from captured settlers’ children, kidnapped from wagon train raids?

So, I married my distant cousin? Damn.

Me too.

There were no white settlers in that area at that time. Nearest town was St Louis.

Both of your parents are your ancestors, but you only got half of each of their genome.

You have 23 chromosome pairs, and that’s not an even number.

The closest split you’ll get from each pair of grandparents is 12 and 11 (for example, 12 chromosome halfs from grandpa, 11 from grandma).

Each of us has 64 (or fewer, with knotted family trees) great-great-great-great-grandparents, and each of them is indeed your ancestor, but you only carry chromosomes from 46 of them.

My eye doctor once said...Behind every brown eye is a blue eye.

That's not what my eye doctor said.

My eye doctor said everyone with brown eyes is full of crap.

Everyone with blue eyes is a quart low.
