Do you look more like your mom or more like your dad? Why do grandchildren sometimes look just like their grandparents? It all depends on inherited traits, which are passed down from generation to generation. Keep reading to learn more about inherited traits and how they impact nearly everything about you.

What Are Inherited Traits?

Inherited traits, also known as hereditary traits or family traits, are genetic characteristics that you get from your parents. All living things get half their genes from one parent, and half their genes from the other parent. However, only one of those genes shows up as an inherited trait in an organism.

For example, if a mother dog has long hair and a father dog has short hair, their puppy will have the inherited trait of either short hair or long hair. The mixture of genes in the offspring of living things makes every organism on Earth genetically unique.


Examples of Inherited Traits

Animals pass down traits that include camouflaged fur, thick protective scales and attractive feathers for finding a mate. Human genes work the same way. Some traits, such as hair, eye and skin color are polygenic traits — meaning that there are multiple genes that determine their color. Take a look at these common inherited traits that children receive from their parents.

Hair Color

If your mother has blonde hair and your father has black hair, you probably have genes for both colors. But only one trait shows up in your hair color. You may even have a different hair color from your parents, which happens when a trait from a grandparent becomes an inherited trait.

Eye Color

Brown eyes are a dominant allele (one of a pair of genes), so if one of your parents has brown eyes and the other parent has blue eyes, you're more likely to have brown eyes. However, if one of their parents had blue eyes, that recessive trait may be passed to you, giving you blue eyes instead.


Skin Color

If a person with very light skin has children with a person with very dark skin, the children often have a skin color that is in the middle of their parents. That's because there are at least three genes that determine skin color. The children receive both light skin alleles and dark skin alleles from their parents, making their skin color a combination of their parents' skin colors.


Left-handedness tends to run in families, meaning that it appears to be an inherited trait. Scientists have found that both genes and environment have a part in deciding what hand you prefer to write with. However, if you have a left-handed parent or grandparent, you're more likely to be left-handed than someone with only right-handed parents and grandparents.


Bone Structure

Has anyone ever told you that you look just like one of your parents? That may be because you inherited their bone and facial structure. A parent with high cheekbones may pass that down to their offspring, as would a parent with a large nose or a prominent chin. Even the bones in the rest of your body are passed down from your parents.


Doctors often try to predict how tall children will be based on their parents' heights. Children typically end up between their parents' average heights, though environmental factors such as nutrition can play a part as well. If you are much taller or much shorter than your parents, look further back in your family tree to see if you can find similar traits in your ancestors.


Other Inherited Traits

There are many more inherited traits that you get from your parents. Chances are, if you have one or more of the following traits, your parents and/or grandparents do as well.

  • tongue rolling - Parents who can roll their tongues often pass this trait down to their children.
  • colorblindness - Children (usually boys) with red/green colorblindness receive the gene from their mother.
  • widow's peak - If one of your parents has a widow's peak where their hair comes to a point on their forehead, you might have one too.
  • fraternal twins - A woman's ability to release two eggs at once, resulting in fraternal twins, is an inherited trait (which is why fraternal twins run in families).
  • hitchhiker's thumb - Does your thumb curve when you give a thumb's up? See which one of your parents' thumbs does the same thing.

You can probably think of hundreds of additional traits that you share with your parents. The list goes on and on!


Inherited Traits vs. Acquired Traits

But what about traits like sports skills or loving spicy foods? While these traits can also run in families, they are known as acquired traits or learned traits. You pick up these qualities as part of being in a family or by simply being alive. Examples of acquired traits include:

  • disliking scary movies
  • cooking skills
  • sense of humor
  • scars from injuries
  • straight teeth from braces
  • ability to play guitar
  • love of reading

Acquired traits may rely on a genetic component — for example, children who are good at sports may have inherited their muscle mass and strong eyesight from their parents. However, many acquired traits come from normal life development.

It's (Sometimes) All in the Genes

Understanding more about your genetic roots can help you learn more about yourself. Once you see what traits you share with your parents, you can look at all the living things in the world with the same perspective.
