Whatg about what they used to call “throw backs...

My mother had grey/green eyes and so did most of her siblings...my father had blue eyes and so did most of his siblings and his parents...

my brother has blue eyes as do his children, one sister green eyes and brown eyed chidren though their father has blue eyes...

my other sister and I have brown eyes which my mother sid was a “throw back” and that she had an aunt with brown eyes..

I have a brown eyed child ..

and a blue eyed child with blue eyed children..

If some chromosome was missing in me, it managed to find its way hiome...

I believe what you are trying to say is that the chromosome was dormant and not missing...

If you knew the arguments I had from stupid people who told me my son could notpossibly be my own off spring because of his blue eyes...

There’s such a thing as a recessive trait, and that can travel unnoticed / unexpressed for generations, then suddenly pop up. What I’m saying in that diagram is, normally people have 46 chromosome pairs, which means that (at least) 18 of the gr-gr-gr-gr-grandparents haven’t passed down ANY chromosomes at all to you.

Same deal here. Blue eyes me, my one offspring, my father. No one else in each side of each family has blue eyes. Brown or hazel are dominant.
Good,old fashioned Punnet squares might offer a clue.
But DNA is a miraculous thing. It carries everyone you ever were since time began. Genetic memory.

It's simple. Draw a square and make four squares inside. Then you have a 25%, 50%, 75%, 100% probability of a particular gene being dominant.

I am supposed to be going bald and grey at over 55 based on my genealogy but that isn't happening. I am in the 25% square. I have brown hair growing without grey and must get haircuts when it looks bad and shave every day. My cousin went bald at 45. I guess I rolled an 11 on the dice roll:)

I have some relatives that have very dark hair and dark brown eyes (husband and wife). They had a son.. bright blue eyes, blond hair and very fair. He is the spitting image of his grandfather! It’s amazing how that works.

2 brown eyed people could have a blue eyed baby...it depends on if they both had brown eyes but carry the recessive blue gene...There are many degree's of brown eyes...Deep colored brown such as with African Americans its harder to get blue eyes...they would have to have some white or asian blood in their ancestry. Brown eyes are dominate, but could be hetero zygot or homozygot. Genetics is fascinating.

In that case with brown eyed children if they had 4 children I would be homozygous, carrying only brown eye genes, 2 of the offspring would be brown eyed...but carry the recessive blue eyed gene and 1 would be blue eyed...pure recessive gene... Biology 101 in college course on the genetics of passing along certain characterics like eye color...

I had a wild turkey fly into my turkey pen where I was raising Royal Palm Turkeys....All white with a black edge on each feather. A specific breed of turkey..Had to put on heavy gloves to separate the two toms fighting. It was a bloody mess...I took the wild one and put him in a room in the chicken coop where I had a Royal Palm tom (too young to breed) and a female royal Palm....All offspring looked like wild turkeys but carried the recessive gene for the royal palm turkey..But in breeding them back some were wild in color but carried the recessive gene for white feathers with black edges, some were pure royal palm and others came out with cocoa brown feathers like nestles cocoa...looked like neither parent. Brown eyed people can have blue eyed children. Depends on wherether the eye colored gene was homozygote or heterozygot..

Hope this is not too confusing...
