“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.
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. Both parents with green eyes: 75% chance of baby with green eyes, 25% of baby with blue eyes, 0% chance of baby with brown eyes.
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, a quarter of the children will have blue eyes, and three quarters will have brown eyes.
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.
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.
First, the answer is yes to both questions: two blue-eyed parents can produce green or brown-eyed children. Eye color is not the simple decision between the brown (or green) and blue versions of a single gene. There are many genes involved and eye color ranges from brown to hazel to green to blue to…
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.
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.
Yes! Grandparents' eye color can also impact baby's eye color. Baby eye color is genetic, and genes pass from generation to generation.
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.
But what happens if a child has blue eyes and his parents both have brown eyes? The child inherited two blue genes; although neither parent had blue eyes, it was still part of their DNA. Blue eyes can skip a generation. In other words, this child's grandparents' eyes were probably blue.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. Today, scientists have discovered that at least eight genes influence the final color of eyes. The genes control the amount of melanin inside specialized cells of the iris.
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.
Both parents have to pass along the blue eye gene in order for their child to have blue eyes. That doesn't necessarily mean that the parents themselves have to have blue eyes; it's possible they carry the gene, but it is recessive. However, a blue-eyed child is almost certain if both parents have blue 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.
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.
If the two alleles of a specific gene are different (heterozygous), the trait that is dominant is expressed (shown). The trait that is hidden is called recessive. Brown eye color is a dominant trait and blue eye color is a recessive trait. Green eye color is a mix of both.
Blue Eyes are More Sensitive to Light
Melanin in the iris of the eye appears to help protect the back of the eye from damage caused by UV radiation and high-energy visible “blue” light from sunlight and artificial sources of these rays.
Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes. However, if one parent has green eyes and the other blue, your child will most likely have green eyes, as green is dominant over blue.
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
If they both do, that child would be bb and have blue eyes. This is also where your question comes from of course. By the old genetic rules, two blue-eyed parents would both be bb and so could only pass b to their kids. Blue-eyed parents should only be able to have blue-eyed kids.
Green Eyes
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes.
