A curious adult from California asks: “Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes. Or green or hazel eyes for that matter.
Fact: Two blue-eyed parents can have a child with brown eyes, although it's very rare. Likewise, two brown-eyed parents can have a child with blue eyes, although this is also uncommon.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
Although nearly 75 percent of eye color is controlled by the OCA2 gene, other genes provide a pathway for melanin. These genes can raise or lower melanin levels, causing a child to have more or less melanin than either parent.
The brown-eye gene is dominant and overrides the blue-eye gene, so all the children have brown eyes. However, if the father also carries a blue-eye gene and a child inherits one from each parent, that child will have blue eyes.
Both parents with brown eyes: 75% chance of baby with brown eyes, 18.8% chance of baby with green eyes, 6.3% chance of baby with blue eyes. Both parents with blue eyes: 99% chance of baby with blue eyes, 1% chance of baby with green eyes, 0% chance of baby with brown eyes.
Two brown-eyed parents are likely (but not guaranteed) to have a child with brown eyes. If you notice one of the grandparents has blue eyes, the chances of having a blue-eyed baby go up a bit. If one parent has brown eyes and the other has blue eyes, odds are about even on eye color.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
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.
Yes! Grandparents' eye color can also impact baby's eye color. Baby eye color is genetic, and genes pass from generation to generation.
“Can two parents with blue eyes have a child with brown eyes?” Yes, blue-eyed parents can definitely have a child with brown eyes.
Most people feel as though they look more like their biological mom or biological dad. They may even think they act more like one than the other. And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
A couple's children can have almost any eye color, even if it does not match those of either parent. Currently it is thought that eye color is determined by about six genes, so you can imagine how inheritance of eye color becomes very complicated.
The causes behind this color distribution is due to a combination of melanin distribution in the iris' outer rim and an effect known as Rayleigh scattering – the same phenomenon responsible for our sky appearing blue. While they're more common than green eyes, hazel is still a fairly rare eye color.
Hazel eyes mostly consist of shades of brown and green. Much like gray eyes, hazel eyes may appear to “change color” from green to light brown to gold.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
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.
Genes responsible for hair color come from both parents. Although the genes passed down from a child's parents determine hair color, variations can result in a child having a different hair color than both parents.
Personality Traits
For example, if the father is an independent thinker or risk-taker, it's likely his daughter will have some of those same qualities. Other personality traits such as intelligence, empathy, creativity, and leadership skills can also be inherited from the father.
Two large-nosed parents are likely to produce a large-nosed baby, and two small-nosed parents to produce a small-nosed baby. However, when a large-nosed father produces a child through a small-nosed mother, the baby can have a medium-sized nose, due to incomplete dominance.
Black, Indigenous and People of Color (BIPOC) infants are more likely to be born with dark, usually brown, eyes, though the shade may change slightly during the first year. Caucasian babies are more likely to be born with dark blue or slate-gray eyes that may change several times before the first birthday.
According to studies, newborns of Black, Indigenous, and People of Color (BIPOC) are likely to have brown eyes at birth, while Caucasian newborns are likely to have dark blue or gray eyes. Just like skin color, eye color in babies changes after 3 to 6 months of exposure to light.
