A person w green eyes and a person w brown eyes what color will the child have?

50% BROWN0% GREEN50% BLUEThe brown gene is dominant but if it also carries a recessive blue gene then they can have a blue eyes babyAnswerSince brown is a dominant gene and blue is the recessive gene, the child will usually have brown eyes. My father had brown eyes and my mother had blue eyes. They had three children: two brown eyes and me a blue green or as some call it grey eyed child. Then my brown eyed sister had a child with a blue eyed man and their son had blue eyes. So you really need to check to see if the brown eyed person has a brown or blue eyed parents. If one parent has blue eyes then yes it would be possible to have a blue eyed child. So the answer may lie with the Grandparents of the brown eyed person having the child. Check to see if one has blue eyes. Hope this wasn't to confusing.You can definitly can have green eyes when one parent has blue eyes and the other has brown. My Mother has brown eyes and my Father has blue eyes and i have green eyes and my twin sister has green eyes and he is definity our father. My brother has blue eyes though.

The senario in this question is an impossible one. If a person is born with blue eyes the person will always have blonde hair, its as simple as that. A person still may have blonde hair and not blue eyes, but if a person is born with blue eyes, then the person's natural hair color is blonde. To answer the question, the child will be born with blue eyes and brown hair.
