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.
Moreover, can parents with brown eyes have a child with blue eyes?
Yes, it's entirely possible for two parents with brown eyes to have a blue eyed offspring. This is due to dominant and recessive genes, and heterozygous and homozygous genotypes. If each parent has one allele (gene) for brown eyes and one allele for blue eyes, their child has a 25% chance for two blue eye alleles.
Are brown or green eyes more dominant?
And because green eyes are determined by a separate gene. *In genetics lingo, we say that brown is dominant over blue and green. And that green is recessive to brown but dominant over blue. Blue is recessive to both.
Which parent determines the eye color of baby?
If you received a blue allele and a brown allele, your eye color would be brown because brown is the dominant allele. If you have blue eyes, that means you received blue alleles from both parents. Your genes also determine your eye color by dictating how much (and where) melanin is produced in your iris.
