The reason I ask is because I have hazel eyes and my Husband has blue eyes and I was wondering what color our kids eyes might be?

  1. A) Dominant and recessive relationships are all relative and dependent on the level at which you're measuring phenotype.
    B) Dominant and recessive relationships are not the only relationships two alleles may have.
    C) I'm fairly certain that people don't actually have a handle on the allele causing hazel eyes or how it works.
    D) There are many many genes which interact to produce even "simple" phenotypes. There is a whole range of "hazel" colours, colours of blue, and colours of brown, and because not all eye colours are discreetly a single, simple colour, it's very hard for people to understand them. Blue and brown are relatively easy categories with a relatively simple phenotypic relationship. Because some eye colours fall, by nature, into the category of quantitative genetics, they don't necessarily follow simple Mendelian inheritance patterns anymore. As well, environmental effects or other genetic interactions can determine the penetrance or expressivity of any trait.

    Short answer: people actually still don't understand hazel eye colour. Interactions of a number of other genes and their dominant and recessive relationships likely have a lot to do with it, so, because we don't know what those genes are and what alleles you have for those genes, it's not entirely possible to predict eye colour of progeny.


  2. How can that be? My mom has brown eyes and my dad has blue. Both of my brothers have blue eyes, and I have hazel.

  3. Hazel eyes are dominant to blue.  Blue eyes are a recessive trait.  For your child to have blue eyes you would have to carry a recessive gene for blue eyes.  If one of your parents has blue eyes you would have inherited from them the recessive gene for blue eyes.  Every other eye colour is usually dominant to blue including hazel and green eyes.  Brown eyes are dominant over all other eyes colours.  This is a simplified answer.  Genetics can do strange things.
