Yes, they can have a green eyed child if for instance the grandmother/father had them. The genes can skip a generation, so do hair colors. The brown gene is dominant. I have hazel (brown and green) eyes. My mom has blue (as blue can be) my dad has brown (as brown as brown can be)......The father to my first born has dark blue eyes, and my son wound up with his color. My husband, the father to my 2nd born has brown eyes (again brown as brown can be) and my daughter wound up with blue eyes. My husbands grandfather has blue eyes. So, you see- the blue skipped my husband, but got passed on to his daughter. It happens.
Certian color traits are dominant. Brown over blue. Blue over green. Brown hair is dominant over say blonde and blonde is dominant over red. Black is also a dominant color trait.
When the 2 colors cross there is a possiblitity to get a mis...say a red head and a blonde or dirty blonde, you can get a strawberry blone, or light brown. Green eyes, brown eyes = hazel eyes.
Anything can happen!

Eye color is polygenic, meaning that many genes control the amount of pigment in the iris. Brown has the most pigment, followed by light brown, hazel, green, gray, and blue, with the least amount of pigment. Brown eyes are dominant to blue eyes; however, someone with brown eyes could carry recessive traits for green or even blue eyes. Since recessive traits are hidden by dominant traits (they don't show), a brown-eyed couple could carry the hidden genes and give birth to a blue-eyed child without the intervention of a milkman. Just like a brown-haired couple could have redheads and blondes. It would be more likely for them to have brown-haired children, but it's certainly possible and not uncommon to have children with different hair/eye colors.

On the other hand, when you are looking at parents exhibiting recessive traits, it is likely their child will have the recessive traits. That is because the recessive traits only show up if there are no dominant traits to hide them. Therefore, if both parents have blue eyes, the child will more than likely have blue eyes. If both parents have red hair, the child will probably have red hair.

I hope this helps and isn't too confusing.

Yes. There are over 60 color variations of the human iris. Genetically, the darker the eye color, the more dominant (Similar to hair color). Black would dominate over brown which dominates over blue, with all kinds of color combinations in between. Pink eye color is total lack of pigment.
Even though a Punnett square can predict to some extent what eye color the offspring will have, it is an oversimplification. Generally speaking, a pure brown eyed dad and blue eyed mom should have all brown eyed kids. However, various other shades ,can arise. Look closely at someone's iris; you will see that it is not a pure color, but composed of little specs of coloration (something like the cartoons in the newspaper).

Yes. Their child could have brown eyes, blue eyes, green eyes, hazel eyes...sometimes even one blue and one brown eye. The brown eyes are traditionally thought to be dominant, but often brown eyed people also have a gene for blue eyes, so that leaves room for a lot of variations.

I would think it is possible f both parents had a recessive green eyed gene. then the chances of having a green eyed child would be 1:3
B=brown gene
C=blue gene
g=green gene

this would be their punnet

Parent 1= Bg
Parent 2= Cg

BC | Cg
Bg | gg

gg=green eyes
BC= codominance between the two colors, so both would show
Bg= brown
Cg= blue

so out of four kids, two would have brown, one could have hazel, one could have green, but these possibilities are for each developing kid

i learned in biology that blue eyes were recessive, so the child could only have green eyes if green was a dominant allele, which it isn't. the child will have blue or brown. but not really sure what would ahppen in the example below

ex. if the dad is homozygous blue (bb) and the mom is heterozygous for dominant brown B and recessive green (Bg)

possibilities: Bb = brown, bg = blue-green??

No, the dominant gene takes over and the child either has brown eyes or blue eyes. My parents have gray eyes and blue eyes, and my eyes change color between blue, green, and grey.

yes, if the parent genes are heterozygous blue and brown. for example

father's gene is BrGr and mother's gene is BlGr.

using punnet square the possible gene combination of their offspring are BrBl, BrGr, BlGr and GrGr. therefore there's a possibility of getting homozygous Green. as of now i dont know which one is dominant.

My Mother's eyes were hazel and my Dad's eyes are pale blue and I ended up with green eyes.
Both my son's have brown eyes like their father,

try doing on of them things called a punnet square
