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.
Eye color is mostly genetic. One specific chromosome is largely responsible for determining your baby's eye color. It carries two genes, one that determines the amount of melanin in the iris, and the other that controls the activity of the melanocytes. These genes work together to create your baby's eye color.
It is possible for two blue-eyed parents to have a brown-eyed child. Blue eye color is recessive while brown eye color is dominant. So, if the gene for brown eye color is present in the parents' DNA, then it is possible for their child to have brown eyes.
Babies inherit multiple pairs of genes from each parent that play a role in appearance. These genes determine hair color as well as eye color and complexion. And although scientists have yet to determine how many genes ultimately determine the exact color of a child's hair, they do understand how the process works.
Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
"Our research, on a much larger sample of babies than Christenfeld and Hill's, shows that some babies resemble their father more, some babies resemble their mother more, and most babies resemble both parents to about the same extent," says Paola Bressan, a psychologist at the University of Padova in Italy who co- ...

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.
Because boys have the sex chromosomes XY, they must inherit their Y chromosome from their father. This means they inherit all the genes on this chromosome, including things like sperm production and other exclusively male traits.
Determining the rarest eye color... not so straightforward
Green is the rarest eye color of the more common colors. Outside of a few exceptions, nearly everyone has eyes that are brown, blue, green or somewhere in between. Other colors like gray or hazel are less common.
Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount of melanin in the front layers 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.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Boys, on the other hand, only receive a Y chromosome from their father and an X chromosome from their mother.
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. However, since eye color is polygenic, several other genes exert their effects as well.
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.
Yes! Grandparents' eye color can also impact baby's eye color. Baby eye color is genetic, and genes pass from generation to generation.
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.
As more melanin develops, the eyes can darken to green, hazel, or brown. Predicting when your child's eyes will stop changing color can vary. “The range of time when a baby will develop their 'true' eye color varies, but it usually happens between six and nine months of age,” Dr. Zepeda says.
An article in Scientific American explains how the entire theory of newborns looking like their dad due to evolution and fathers recognizing their offspring at birth and during caveman days isn't true – according to current studies.
According to an old notion, first-born children are genetically predisposed to appear more like their father. It was thought that this was done so that the father would accept the child as his and provide for and care for them. Another argument is that this would prevent him from eating the baby.
Children often look like some combination of their parents. This is because each parent gives the child some of themselves {gene}. A child is made from the information found in the cells of the parents. These characteristics are called genes.
The size and shape of your nose may not be genetically inherited from your parents but evolved, at least in part, in response to the local climate conditions, researchers claim. The nose is one of the most distinctive facial features, which also has the important job of conditioning the air that we breathe.
