Can a brown eyed father and a 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.
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.
Why do I have blue eyes but my parents have brown?
Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child. Genetics is so much fun! … Two of the most important genes in eye color are OCA2 and HERC2.

Is eye color inherited from the mother or father?
In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby’s eye color is determined by the parents’ eye color and whether the parents’ genes are dominant genes or recessive genes.
How do I know if I carry the blue eye gene?
The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. … If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes.
What do daughters inherit from their fathers?
#4 X-Linked Traits (for Daughters)
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.
What nationality has green eyes?
Green eyes are most common in Northern, Central, and Western Europe. About 16 percent of people with green eyes are of Celtic and Germanic ancestry.
Are blue eyes a sign of inbreeding?

If both parents are brunette, they can only have a blonde child if they both carry the recessive blonde trait. But even if they do, the chance of giving birth to a blonde is just one in four.
What color eyes are dominant?
The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
Is Hazel considered brown or green?
Hazel eyes are due to a combination of Rayleigh scattering and a moderate amount of melanin in the iris’ anterior border layer. Hazel eyes often appear to shift in color from a brown to a green.
