Red hair, like blonde, is recessive. Somewhere in both of your parents' families, there was red hair.

My parents both had red hair and of their seven children, only one (I) had red hair. I married a redhead and we have three redheads - but we could as easily have had none.


Somewhere. None of my aunts, uncles, cousins, grandparents have red hair.

Maybe PP was right about the mailman.


PP here. It could be generations back. My DH's father was a redhead, but his mother had brown hair, and no one in her family had red - and yet, DH and his sister are redheads.

I think you do need it on both sides of the family, somewhere, in order to produce a redhead (which is why red hair is relatively rare).

I find red haired men sexually repulsive. Ugh.

My husband has hazel, I have green and our two sons have blue and brown. The third is on the way. Any bets?

Recessive genetics: Two blue eyed parents can only have blue eyed children. (unless their eyes are not really blue, but are grey --that is a dilution of the brown gene) Green eyes are a mix of brown + blue gene. Dilution gene is an aspect of another gene -- make it lighter, and is recessive.
True blondes, who remain blondes in adulthood without a trip to the hairdresser: If both parents are true blondes, all off spring will be blonde. Blonde + recessive dilution gene = white blond hair.
Blonde as kids, brown as adults have dominant brown gene. It is possible to have a double recessive blonde hair child, but (80% against) unlikely if both parents carry the brown gene. Genetics!



So, if I have blue eyes and my DH has green eyes, can our child have brown eyes?


Yes.

This is oversimplified and kind of incorrect. Eyes are either pigmented (brown) or unpigmented (everything else). There are several genes that determine the exact shade of unpigmented eye. Two blue-eyed parents can have children with hazel/green/grey eyes. The genes that determine eye color are also very susceptible to mutation. Unpigmented eyes were likely a mutation somewhere in human ancestry, or else we would all have brown eyes.

For the record, I have unpigmented eyes and they have changed color over the years from caramel-brown to amber-green. My DC's eyes are blue-grey.

I have a neighbor who is multiracial but appears black, with quite kinky hair that would 'fro if she let it (her words). Husband is strawberry blonde with those translucent eyebrows/lashes that look like the person has -no- eyebrows.

Kids are tow-headed blonde, Italianish skin. SAHM friend is assumed to be the nanny 100% of the time! during 9-6 hours, she says.

I wouldn't take it personally. People love easy jokes--they can't help themselves. I have four kids, three of whom look just like their dad and one of whom looks like neither of us. People make the mailman joke all the time. Even, I make it.

So...I would say take a wait-and-see approach -- children's hair and eye color is so mutable.


Interesting. Is the Asian the mom or the dad?

I am Asian and my son was born with light brown hair and brown eyes, which haven't changed. His dad was tow-headed as a kid with blue eyes, and now has dirty blond hair. Everyone in his family has either blue or green eyes. I have another child who is full Asian and her hair and eyes are much darker than my hapa's.


I am the mom and I am white, was born with white-blonde hair and now have brown hair/green eyes. DH is Asian, standard black hair/black eyes.

Red hair and blue eyed baby became blond and green eyed.
