Question:

Is it possible to inherit eye colour from great grand parents ?

how to explain that out of the dads 1 brother and 3 sisters, his brother and one of his sisters has green eyes when nobody in the past generations in our family has had green eyes. they all had dark brown.
Also my dad has quite dark skin(brown) and my mum has yellowish skin but my sister is fair/white skinned.
Is this all not strange, and does it indicate that the characteristics of a baby are not always hereditary.....

Best Answer - Chosen by Asker: Absolutely. Genetics and heredity are a crazy this to study, and scientists have pretty much proven that anything is possible. My mom's parent's proved that brown eye color is dominant theory is bogus when they had three children, two with green eyes, one with blue eyes. My grandfather had green eyes, my grandmother had dark brown. My son's eye color is the color of my mothers. They look nothing like mine of his fathers. Anything can happen, and I truly believe you can go back several generations to find where the traits come from.
