Flexi Says: Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby. If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation.
Brown eye colour is dominant over blue eye colour. Therefore, for the brown-eyed parents having blue-eyed child, the possibility is that both have heterozygous genotype i.e. Bb. Therefore, from the square below, it is clear that there is a 25% possibility of blue-eyed (bb) child.
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.
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.
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.
What is the rarest eye color? Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
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.
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.
A condition is considered Y-linked if the altered gene that causes the disorder is located on the Y chromosome, one of the two sex chromosomes in each of a male's cells. Because only males have a Y chromosome, in Y-linked inheritance, a variant can only be passed from father to son.
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.
Blue eyes come from your genetics and, more specifically, one ancestor—one that both of your parents share. Contrary to popular belief, eye color doesn't come down to just your parents (although their eye color can be a factor).
If you and your partner both have brown eyes, your baby is highly likely to have brown eyes. If one of your baby's grandparents has blue eyes, your baby's chances of having blue eyes is higher. If you have blue eyes and your partner has brown eyes, or vice-versa, your baby's odds are about even for either eye color.
The brown version of gene 1 is dominant over the blue one. Dominant means that if at least 1 of your two copies is brown (Bb), then you will have brown eyes. Geneticists represent the different versions of the eye colour gene as B for brown and b for blue (the capital letter is the dominant, the lowercase, recessive).
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.
From the statistics presented, it is clear that brown hair and eyes are the most common combination globally. Blue eyes are also relatively common, with 8% of people having them worldwide. On the other hand, red hair and blue eyes make up a very small percentage of the population at less than 1%.
If the father passes on an X chromosome, the baby will be genetically female, and if the father passes on a Y chromosome, the baby will be genetically male.
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.
When we casually observe via our eyes, we may feel that we have inherited most of our hair features from either our mom or dad. However, the reality is that we inherit equal volume of genetic information from both mom and dad.
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.
Unfortunately, unless you were born with blue eyes, there aren't any ways to naturally change your eye color. However, you can create the illusion of having blue eyes. We've answered your questions about getting blue eyes so you can keep your eyes safe and healthy while experimenting with different colors.
Genetically, a person actually carries more of his/her mother's genes than his/her father's. The reason is little organelles that live within cells, the? mitochondria, which are only received from a mother. Mitochondria is the powerhouse of the cell and is inherited from the mother.
