Eye and Hair Color genetics thread

Last posted Jan 17, 2013 at 07:01PM EST. Added Jan 15, 2013 at 09:07PM EST

In this thread, list members of your family, and their eye and hair color.

You can list as many family members as you want.

If you have a heterosexual husband, wife, lover, etc, list their (as much as you know) family with eye and hair color, so I can predict your children’s eye and hair color.

Remember, that when listing cousins, aunts, and uncles, you have to also specify what side of the family they come from.

If any of you had genetic tests, I would like to know the result for eye and hair colour.

The answers that I will give
A= Gene for dark eyes
a=Gene for light eyes
B=Gene for dark hair
b=gene for light hair.

Please allow some time for my analysis of the possible genetic combinations in your family tree.

I will post my family’s eye and hair color an hour later.

I’m a total mutant. I have all recessive traits and look nothing like my parents for the most part. Either I’m baby swapped (I have proof that I’m not adopted) or I’m all recessive. Some of the traits I have on either side of my family haven’t shown up in 2 generations and only showed up with me. Pretty odd if I’m honest…

That’s pretty amazing.

The chances of that happening are pretty slim.

If you are blond and blue eyed, and your parents are dark haired and dark eyed, then it means that:

Blue eyes, dirty blonde (so brown?)

My kittens:

We didn’t see the dad, and the mom is all black.
3 kittens had tails, 1 was mostly black with some tan and no tail, and 1 regular no tail.

Any clue of the daddy?

I have light hair naturally, however my excessive amounts of time inside since my younger days has left my hair much darker than it is naturally, similar to my uncle. Both my mother and father have dark brown hair, both of their parents had dark brown hair. My mother has brown eyes, my father has gray eyes. I have no brothers or sisters. No one else in my family has green eyes or even close. I have hazel eyes, but their mostly green, small amount of blue and brown mixed in. All family except me has brown or lighter brown hair, had blonde, slowly turned more golden brown and then slowly became dirtyer as I stayed inside more and more. When I go to the beach or something for a week, my hair gets pretty light compared to before I do so.

Your genotype is:
Aabb

Father
aaBb

Mother
AaBb

Blonde hair also includes those that were blonde as a child, but as they grew, became light brunets.

I don’t know about cat genetics, but I know about budgie genetics.

I only know a few cat genes.

Your lover is either aaBb, or aaBB.

If the first scenario is correct:
All of your children will have green or blue eyes.
50% will be blonde.
50% will be brunet.

If the second scenario is correct:
All of your children will be brunet with blue or green eyes.

Wow, this is complex, since you don’t know your father.

Since you come from japan, we’ll assume that your mother and her family have the genotype AABB.

Do you know if your father was a Japanese man or a foreigner.

If he was a Japanese, your genotype is probably AABB.

If he was a blonde, blue eyed man, your genotype is AaBb.

? represents unknown genes.

Your genotype is:

A?B?

Do you have any more information on your family (sibllings, aunts, grandparents) so I can make a more accurate guess?

Based on this information, I can’t give statistics, or accurate gene analyses.

His paternal grandma (my maternal great grandma) is blonde with blue eyes.

Genetic Tests:

I had one. It said my genotype was AABb.

You (according to genetic test):
AABb

Since everybody on your father’s side all have brown eyes and brown hair, and their race is a “dark haired, dark eyed” race with no blondes, it’s safe to assume that they all have the genotype AABB.

Sister
50% chance AABb
50% chance AaBb

Mother
Aabb

Maternal Grandpa
aaBb

Maternal Grandma
AaBb

Aunt 1
33%-AaBB
66%-AaBb

Lover’s Family

Lover
Aabb

Father
aaBb

Mother
A?Bb

Lover’s paternal grandma (your maternal maternal great grandma)

All of your children will be brown eyed. Half will be blonde. Half will be brunet.

Possible Genotypes of children
25%-Aabb
25%-AaBb
25%-AAbb
25%-AABb

I knew all of these when I was nine years old. It’s just the easiest thing to predict.

Right on, I’m onto complex genetics. Like the ‘Make a Master Race’ stuff, if you now what I mean.

Me:Brown hair and light Green eyes.
Mother:Dark Brown hair and Green/Grey eyes.
Father:Brown hair and light Green eyes.

And that’s it.

Your mother and father could have these possible genotypes. I can’t give any accurate statistics, because I don’t know about the rest of your family.
aaBB
aaBb

If both of your parents are aaBb, then these are the chances of your genotypes.
66%-aaBb
33%-aaBB

If both of your parents are aaBB, then here are the chances of your genotypes.
100%-aaBB

If one parent is aaBB, and the other is aaBb, here are the chances of your genotypes.
50%-aaBb
50%-aaBB

We can say that:
aaBb=33%

Do you have any blonde siblings, grandparents, or aunts?
