For someone who knows...

I don't know if this post belongs here, but I don't know where else to post it. I have a question about genetics. What is the likeliness of a green eyed father and light blue eyed mother having a dark brown eyed baby? Especially, if the grandparents and great grandparents for two generations back on BOTH sides have blue and green eyes. The siblings of the dark brown eyed baby, have blue and green eyes. I was told yesterday that it is almost genetically impossible.

I would encourage you to go to the following page and read the whole thing for a more detailed answer. I found it most interesting! :)

Here is a snippet from the page:

Is eye color determined by genetics?
https://ghr.nlm.nih.gov/primer/traits/eyecolor

Researchers used to think that eye color was determined by a single gene and followed a simple inheritance pattern in which brown eyes were dominant to blue eyes. Under this model, it was believed that parents who both had blue eyes could not have a child with brown eyes. However, later studies showed that this model was too simplistic. Although it is uncommon, parents with blue eyes can have children with brown eyes. The inheritance of eye color is more complex than originally suspected because multiple genes are involved. While a child’s eye color can often be predicted by the eye colors of his or her parents and other relatives, genetic variations sometimes produce unexpected results.
