Childs Eye Color

Anyone see this yet? http://museum.thetech.org/ugenetics/eyeCalc/eyecalculator.html

It can tell you the chances of your child having a certain eye color

That's cool.  It says I'm most likely to have a brown eyed child-I do, then a green eyed child-which I also have. And says I'm unlikey to have a blue eyed child-which I also have, so we must have got lucky with that one.   

My eyes are brown ...brown eyes are a Dominant Trait...so I knew she would be a "Brown eyed girl"

although I expected Jess to be darker skin and with kinky hair so I suspect her children my have those traits when she has her own.

According to that we had a 50% chance of having a brown eyed child, 40.6% green and 9.3% blue. Ethan has green eyes.   I always thought he would have brown eyes because my eyes are brown and like Alicia says brown is the dominat gene but I guess all the green eyes on his dad's side won!

You're a 'carrier' of the recessive gene, Liz, or his eyes would have been brown. Dad can't take all the credit!

My eyes are dark brown.  My parents both have brown eyes.  My husband has blue ones and so does his mom.  This site said all our children would have a brown-eyed phenotype.  Our two year old daughter's eyes are pure pea green w/o a hint of brown.

Well my mum has blue eyes but there are no green on my side, well not in anyone's living memory anyway.

That's based on a Punnet Square, which predicts the outcomes of allele frequencies in offspring. Fantastic stuff! The first time I did one in HS I was hooked!

According to them I can't have green eyes since both of my parents have blue.  Do I need to have a long talk with my Mom?   

Stolen from someone's website: 

Dominant and recessive flavors of genes and the presence of genes on chromosomes that come in pairs can explain the eye color inheritance patterns described here (but remember that there is more to human eye color inheritance than the simple two gene model described here).

The bey2 gene has two flavors - brown is dominant over blue. Each individual has two copies of this gene, each can be one of the flavors. The possible allele combinations for the bey2 gene are: brown-brown, brown-blue, and blue-blue. Of these three, the brown-brown and brown-blue combinations will both produce brown eyes, as brown is dominant over blue. Only the blue-blue combination will produce blue eyes.

But there is a second common gene for eye color - the gey gene. It also has two flavors - green is dominant over blue. In addition, a green allele of gey is dominant over a blue allele of bey2 and recessive to a brown allele of bey. Thus the alleles of the two genes have a dominance hierarchy - bey2-brown is dominant over everything else, gey-green is dominant over bey2-blue and gey-blue but recessive to bey2-brown, and both of the blues are recessive to everything else.

The final piece of the story (and remember, it is just a story, there are more than just these two genes involved in eye color inheritance) is that a child gets one chromosome of each pair from each parent. The bey2 gene is on chromosome 15. A parent with brown-blue alleles of the bey2 gene has a pair of chromosome 15s, with the brown allele on one and the blue allele on the other. This parent could give either the chromosome bearing the brown allele or the chromosome bearing the blue allele to a child. A child with brown-blue alleles of the bey2 gene got the brown allele (and one copy of chromosome 15) from one parent, and the blue allele (and the other copy of chromosome 15) from the other parent.

Got that?

LMAO

How many alleles is eye colour based on, though?  From what I understand, it's a bit more complex than say, blood type.  Is that so?

Mine is almost the same as yours and we came out with mainly brown but possible green or blue.  I wonder why yours didn't.  What colour are his Dad's eyes?

lol!  "Hooke"

boom , boom

sorry...I've inhaled too much Flash while cleaning the bath today...

His dad's eyes are green.  The same shade as Aillidh's, in fact.
