Hair colour and Asperger's

Post Reply New Topic

Thanks for those links rdos, most helpful as I was unable to find the information I was looking for.

I put blonde because you didn't have a choice for blonde with red in it. Wouldn't it be a case of whether you carry the red haired gene? It's on both sides of my family. For instance, some of us don't have red hair, but those like that if they had children then it showed up in the children. (The red hair I mean)

depends how UV damaged my hair is , after a summer of sun it will be a dark blonde, after a winter fair brown. Now what to vote...

I'm naturally blonde but have been dying my hair red since I was 9 (12 years).

Dark brown but gets auburn bits in and occasionally blonde bits. Long story short: My hair's weird.

And no, the redhead allele will NOT become extinct as you breed with darker-haired people. What will happen is you'll have the 'resurfacing feature' phenomenon. (otherwise known as 'skipping a generation')

Let's start with someone who's homozygotic dominant (dark, let's say brown hair) and breed them with someone who's homozygotic recessive (in this case, red-headed) and see what happens in terms of offspring.

If we let D represent brown hair and d represent red hair this will happen:

DDXdd = Dd ALL of the F1 generation will have this genotype and therefore all have the phenotype of dark hair.

If we then take two of the offspring (Dd x Dd) and breed them then this will happen:

Dd x Dd = DD, Dd, Dd, dd. 25% of the F2 generation will have red hair - 75% will have dark hair. In case people are wondering why I put Dd twice, it's because one is Dd and one is dD but the letter representing the dominant allele is always written first by convention.

If we then do Dd x dd this happens:

Dd x dd = DD, Dd, dd, dd, meaning that 50% of this generation will be redheads.

We can then do dd x dd which can only equal dd so 100% of that lot will be redheads.

And if you apply that to the entire world...you can actually kill off the dark-haired people as opposed to the red-headed people.

And dark-haireds becoming extinct CAN NOT BE REVERSED. Red-heads can be reversed because of that long-winded explantion I gave. (Me like genetics.)

((Generation - shorthand for family generation))

I'm not sure how being a red haired person means you are more likely to have AS.

Anyway, I have black hair.

I have Blond hair but since I'm going bald, I much rather keeping my head shaved as bald as it can go. I hate having any hair in the summer. It's hot and it's icky.

So if I had hair, it'd be Blond.

I voted red, but naturally it's technically auburn. My ID says red, I think. Because when the lady asked for "natural haircolour" and I said auburn, she looked at me like I was nuts and then said "It's red."

WHOA!

My hair is brown. My hair appears kind of black, but pictures, and my mustache shows it is closer to brown. BUT, here are a few little facts! When I grew my beard out, many commented that it was RED! When I was younger(up to about 9-10), I wouldn't really tan. I once got LOTS of freckles(A common Red hed trait)! When I was about 7, a girl slapped me! She accused me of doing something I would NEVER do! When I asked about it, it was revealed that she confused me with a REDHEADED boy! With one picture around that time, my hair DID look redish.

Steve, maybe you have the kind of hair that looks red when the light reflects off it right, (Outdoors), but looks dark under indoor lighting. A few people in my family have hair like this

Brown hair, with AS traits. Was blonde as a child, but my hair darkened over time.

I have black hair

My hair is naturally brown with blonde highlights. It was blonde when I was born, and if I follow the family pattern (which I have no doubt I will), it will be an extraordinarily dark brown by the time I'm 30.
