What determines a baby’s eye color?
Eye color is mostly genetic. One specific chromosome is largely responsible for determining your baby’s eye color. It carries two genes, one that determines the amount of melanin in the iris, and the other that controls the activity of the melanocytes. These genes work together to create your baby’s eye color.
Do grandparents eye color Affect Baby?
If, say, my wife was also blonde and blue-eyed, would it somehow lessen the chances of our children being blonde and blue-eyed? Yes, grandparents’ genes can affect how their grandchildren look.
Can 2 blue-eyed parents have a brown-eyed child?
Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes it possible for two blue-eyed parents to have brown-eyed children.
What nationality has green eyes?
Where Do Green Eyes Come From? Green-eyed people most commonly originate from northern and central parts of Europe, as well as some parts of Western Asia. For example, Ireland and Scotland both boast a whopping 86 percent of the population having blue or green eyes.

Which parent has the dominant gene?
Genes from your father are more dominant than those inherited from your mother, new research has shown.
Can 2 brown eyes make hazel eyed baby?
Not really. Two brown-eyed parents are likely to have a brown-eyed child, but could potentially have a child with blue, green or hazel eyes, depending on the combination of genes from each parent.
How do I know if I carry the blue eye gene?
The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
How much DNA do you inherit from your grandparents?
However, on average, you do have about 25% of your genetic information coming from each grandparent. Your body is made of cells that contain your genetic information, or DNA. DNA gives instructions to your body to develop and function, and it makes you who you are.
