Where does eye color come from Mom or Dad?
If a gene version is dominant, it will dominate whether it came from mom or dad.
So your chances of getting a dominant trait don’t depend on which parent it came from.
If mom gives you the dominant brown eye version of an eye color gene, odds are you’ll end up with brown eyes.
Same thing if dad passes the same gene..
Can babies blue eyes turn brown?
As a general rule of thumb, baby eye color tends to get darker if it changes. So if your child has blue eyes, they may turn to green, hazel or brown. “The changes are always going to go from light to dark, not the reverse,” Jaafar says.
When can you tell a baby’s eye color?
Permanent eye color is not set until a baby is at least 9 months old, so wait until your child’s first birthday to determine what color they will be. Even then, sometimes you may find little surprises. Subtle color changes can still occur all the way up until about 3 years of age.
Can a brown eyed father and blue eyed mother have a blue eyed child?
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. Now mix in a third green allele, which is dominant to blue, but recessive to brown.
How do 2 brown eyed parents have a blue eyed child?
The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby. … Brown eyes + brown eyes = 25%, but only if both parents carry the blue-eyed gene.

Are blue eyes the rarest?
Between 8 and 10 percent of people worldwide have blue eyes. Blue eyes are most common in Europe, especially Scandinavia. People with blue eyes have the same genetic mutation that causes eyes to produce less melanin. The mutation first appeared in a person living in Europe about 10,000 years ago.
What genes are inherited from mother only?
It’s Not Only About the Chromosomes The mitochondrial genes always pass from the mother to the child. Fathers get their mitochondrial genes from their mothers, and do not pass them to their children.
Which parent determines eye color?
The chromosomes a child inherits carry genetic information that determines eye color. Differences in the copies received from each parent causes variations in the amount of melanin produced. A region on chromosome 15 has a big part in determining eye color. The OCA2 and HERC2 genes are located in this region.
Do blue eyes come from mother or father?
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.
Is it true that most babies are born with blue eyes?
While only 1 in 5 Caucasian adults have blue eyes in the United States, most are born blue-eyed. Their irises change from blue to hazel or brown during infancy. … Babies aren’t born with all the melanin they are destined to have.
Can eyes change color?
Eye color is determined by genetics. The eyes can naturally change their color as a response to the iris expanding or contracting in the presence of light or as the iris ages. This results in the eyes gradually becoming darker or lighter in color.
What do daughters inherit from their fathers?
As we’ve learned, dads contribute one Y or one X chromosome to their offspring. Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit X-linked genes from her father as well as her mother.
Are blue eyes a sign of inbreeding?
However, the gene for blue eyes is recessive so you’ll need both of them to get blue eyes. This is important as certain congenital defects and genetic diseases, such as cystic fibrosis, are carried by recessive alleles. Inbreeding stacks the odds of being born with such conditions against you.
