What do blue and brown eyes make?
Someone with brown eyes may be carrying one blue allele and one brown allele, so a brown-eyed mother and a blue-eyed father could give birth to a blue-eyed child.
Can a blue eyed parent and a brown eyed parent have a blue 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.
Do great grandparents determine 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.
Can a child look like a grandparent?
Some people look like their grandparents because they inherit a similar genetic makeup as that of their grandparents. Genes are hereditary; that is, they are passed from one generation to the next, and each individual is a product of his or her genetic composition.
Why did my Grandpa have blue eyes instead of brown?
So, depending on the combination of genes they received from their parents, it’s very possible that a child might not look like either parent. This explains why little Sally has her grandfather’s blue eyes instead of brown eyes like the rest of the family. It really is a genetic lottery of sorts.
Can a blue eyed parent have a brown eyed child?
A common myth is that parents who both have blue eyes cannot have a child with brown eyes because of dominant and recessive genes, but in reality genetic variations sometimes produce unexpected results. Though there is a less than 1% chance of blue-eyed parents having a brown-eyed child, it is not out of the question.
What are the odds that my baby will have blue eyes?
In this way, the odds of eye color options can be calculated. As an example, if both parents have blue eyes, but are carriers of a brown gene, according to all the potential combinations using a 2-gene model, the child will most likely have blue eyes, but has a one in four chance of having brown eyes.
How are green eyes and blue eyes inherited?
So it would appear that you were passed a green gene from your mother and a blue gene from your father. (He has to have two blue genes to have blue eyes.) The Green gene from your mother is more dominate than the blue so you have green eyes.
