What color will a baby's hair and eyes be if the mother has dark brown hair and blue eyes and the father has dark brown hair and dark brown eyes?

Answer:

Brown eyes are dominant but it depends on the grandparents colouration too because the parents have THEIR parents genes. If all the siblings of the brown-eyed parent have brown eyes, there's a higher chance that the baby will have brown eyes too, especially if the blue-eyed parent has pale eyes. As for hair..... most babies are born with the colour hair they will have as an adult, then they lose practically all of it and start off again with hair the lightest it will ever be, gradually getting darker as they age. Females eye and hair colour is usually darker than males. If parents were fair-haired as kids, the children could be too, but if they were dark-haired right through from a very little toddler the baby may have dark hair too.
