Can great grandparents pass eye color?
However, we now know that a child’s eye color depends entirely on genetics. By looking at the eye color of the parents, grandparents and great grandparents, it is possible to predict what color a baby’s eyes will be. However, genetics will sometimes have a surprise in store.
Can my baby have blue eyes if grandparents?
Some seemingly impossible genetics can and do happen sometimes. This means that your kids might get your grandparent’s darker eyes or hair even if you have kids with someone with blonde hair and blue eyes. It just would be much less likely than blonde haired, blue eyed kids.
Can you inherit your great grandparents genes?
Because inheritance is random, one great-grandparent may have passed on 12% of their DNA to you, while another great-grandparent may have passed on only 4%.
Can parents both with blue eyes have a brown eyed baby?
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 are the odds my baby will have blue eyes?

How many generations can genes be passed down?
According to calculations by geneticist Graham Coop of the University of California, Davis, you carry genes from fewer than half of your forebears from 11 generations back. Still, all the genes present in today’s human population can be traced to the people alive at the genetic isopoint.
