How are blue eyes recessive? it's no doubt they are infact a eye mutation, but they do no harm in seeing, my nan and grandad both had brown eyes, with no trace of blue eyes at all, they had 5 children, 2 of them having blue eyes, (no the milkman did not do it.... ) even more of a bigger fact is before 9000 years ago people did not have blue eyes until a individual was born with blue eyes somewhere in the Ukraine. Moving on now over 50% of Europeans now have blue eyes (that's including countries like Greece) so how can blue eyes possibly be recessive?.

Because they had recessive blue eye genes, and the only way you'd know that they had "no trace" is by actually analysing their genes, cuz it's, y'know, recessive. If it had been dominant, they would have blue eyes, and probably the blue eyed ancestors of yours would have brown eyes. Year 9 biology beckons.

Brown + Brown = Brown

Brown + Blue = Brown

Blue + Brown = Brown

Blue + Blue = Blue


That is how Blue eyes are recessive.

This is how they are not recessive, it's true if my nan and grandad both had brown eyes and my father had blue eyes it's pretty obvious they are not, same goes for 50% of the population of europe in 9000 years.

oh my....

Just because somebody has brown eyes doesn't mean they pass on the brown eye gene. They could pass one a green eye, or a blue eye gene. If both parents pass on the blue eye gene, that means the kid's gonna have blue eyes.

Ok here is a good question for you, what if it's 2 black people with blue eyes?

Then they're probably going to have a black kid with blue eyes... Then again, nothing is certain.

Brown/brown+Brown/brown=brown
Brown/brown+brown/blue=brown
brown/blue+brown/blue=3 brow to every 1blue.
Blue/blue+blue/blue=blue.
brown/blue+blue/blue=2 brown to 2 blue

That's a more acurate picture of how genetics works. See brown represents a dominant gene and blue represents the recessive. When a person with brown and no blue eyed genes has a kid with someone with blue eyes that kid will have brown eyes but will still have the dormant blue eye gene. Now even if he has a kid with a woman with brown eyes it is still possible to have a kid with blue eyes if that woman had the same dormant blue eye gene.

Here's why it's recessive:

Both you grandparents had the dominant brown eyed gene, represented by "R". However, they also had a recessive blue eyed gene, represented by "r". Each of them passed on only one of these genes. So we end up with a diagram like this one:

____R____r__
R___RR__Rr__
r___Rr___rr__

Now given that your dad had blue eyes, one can assume that the recessive genes were passed on from at least one of your grandparent, so even though blue eyes are recessive, they still ended up showing themselves. Mmmkay?

sure it started as a mutation, but a sit did not hinder the mutated populations growth it stayed alive, but if you have brown AND blue eyed genes, you will over 50% f the time get brown eyes.

Okay, I know this has just been explained multiple times, but I'm going to try it with different wording, just to ensure that this makes sense at least once.

You have two eye-color genes. Only one actually dictates what color your eyes are; the dominant one. So if you have a blue gene and a brown gene, you have brown eyes. When you pass on your genes, you only pass on one of those two genes, and it isn't necessarily the dominant one; the other parent supplies the second gene for the child. So if your mother had brown/blue, and your father had brown/blue, then they would both show brown eyes. But, if they both passed on their blue gene, you'd have blue/blue, and with no dominant brown to overpower the blue gene, you would have blue eyes.

Mutation? Where's the arguement for evolution?

If it is so recessive then howcome if 2 brown eyed people reproduce they have a chance of having blue eyed kids and green eyed kids yet if 2 blue eyed people reproduce they will definately ahve blue eyes, i'm starting to believe what people tell me are true about blue eyes being recessive but if so why did they come into the world in the 1st place is what i don't understand and that blue eyed people can carry on having blue eyed children even if the gene is supposedly recessive. Maybe some blue genes are stronger than other blue genes or some blue genes could possibly be as "strong" or stronger as brown genes, In no way am i saying this is true or i believe this, i'm just saying this as a possibility.

Ok, i kind of understand now thanks.

Glad I could help. I know it's counter-intuitive... People expect that "recessive" means the actual gene goes away, when really recessive genes are just as likely to be passed on; they just won't show up as often when they're there.

Sir do i have entitlement to speech?, i said in another post on this thread that i do not believe in what i say, i'm just bringing forward a theory, that is probably not correct but is worth a debate without someone commenting on the mentality of other people.

Because people who have blue eyes have no brown gene to overpower their blue gene and therefore will always have blue eyed kids. However brown eyed people can have a recessive blue gene that may be passed on and either remain dormant under a brown eye gene or come into contact with another blue eyed gene giving that person blue eyes.

It came into the world as a mutation. this mutation like many in the past that are actually the reason we are human beings today (assuming you believe in evolution) was able to survive and spread eventually so that a substantial number of people had it.

More common sence but in the world of science common sence probably does not account for much...
