No 5hit. I seriously hope the Mod edited that post to remove something more terrible than that. :roll:

Not impossible nor improbable. Each parent inherited two set of genes, one from each of their parents. If both receive a gene for brown eyes from one of their parents, then those two having a blue eyed child would be unlikely(whats unlikely here is that they would have brown eyes). if only one received the gene for brown eyes, half their children will have brown eyes. For those that say everything thing they have learned tells you this is not possible, I hate to break it to you, but you were not paying attention in class.

otherwise that would be extremely dickish

I know a number of people who should have blue eyes but they are so full of sh!t they are brown.

I am thinking the Mod maybe the OP or knows the person/peopel they are talking aboiut. But I hope it was soemthing edited. :roll:

Well, although I learned the same dominant/recessive gene logic in school - there are a lot of variations to eye color. If the only choices you had were BB, Bb, bB, and bb, then there would be no variations of browns and greens. I think the fact she has light green means she's got a rarely used dominant gene that contributes to brown eyes.

Either that, or she had an affair.

it is a bit more complicated than that

dumb mods! I hope Anand starts hiring some new mods cause i've been seeing too many unnessary bans. But I guess that's happens when you give a kid a gun.

Eye color is more complex than two genes

In humans three genes involved in eye color are known. They explain typical patterns of inheritance of brown, green, and blue eye colors. However, they don't explain everything. Grey eye color, Hazel eye color, and multiple shades of blue, brown, green, and grey are not explained. The molecular basis of these genes is not known. What proteins they produce and how these proteins produce eye color is not known.

Cool! My eye color is unexplained.

ZV <-- Hazel

Maybe the mod is having/had a similair issue and is wondering if he's the father/wasn't the father?

I work with Scar and he's still banned, and no there wasn't anything edited in that post. I guess the mods are having a bad day.

Whoa-ho everybody dance, moonbeam has traipsed through. I believe you have a bit of P&N sticking to your shoe my friend, use the scraper at the door next time.

nothing. it was during the software problem they had the other night. anyone who started a thread asking about it got banned until they could sort things out.

The gene for blue eyes is a mutation of the gene for brown, so it's always possible for a blue eyed gene to mutate right back to brown.

Not many things are actually.

Yes, blue eyes are recessive, but that doesn't mean that one trait from your past relatives gets past down instead. It is rare, but it is possible.

Genetics isn't as simple as that, especially in human DNA. While it is very unlikely for two light eyed people to have a brown eyed child, it isn't impossible. Also, depending on the age of the child, her eye color may change as she gets older.

Basically.

That is flawed.
The gene for Brown eyes is dominate over the gene for blue eyes. A person with Blue eyes has NO Brown eye genes. However a person with Brown eyes can have a blue eye gene.
