How many times have you picked out striking features that you and your siblings share? Maybe you and your mother have the same charming smile. Perhaps your dad has always told you you’ve got your grandmother’s eyes. What about your bright red hair that nobody else in the family shares?
Some traits are easier to trace back to specific individuals than others. The truth is, though, that the science behind these inherited genes is far more complicated than pointing out two people’s similar smiles. When you get down into the nitty-gritty, it’s exceptionally hard to tell where all your traits come from.
Thankfully, scientists have been able to pinpoint how we pass some of our genes on. There are three main ways in which this happens. You can inherit traits through a dominant gene, such as your eye color. If your father has brown eyes while your mother has green eyes, you will get the dominant gene- in this case, you’ll end up with brown eyes.
You may also inherit recessive genes. In this case, both your parents need to have it in order for you to inherit it. Going off of the earlier example, if you have blue eyes then both your parents are carriers of the same recessive gene.
And finally, there are traits, known as X-traits that may only be passed down to you through your mother as these are only ever found in X chromosomes.
But that’s not all there is to it! In some cases, some of your traits have developed due to your environment. Now that some light has been shed as to why we look the way we do, let’s get into 6 surprising things you didn’t know you inherited from your parents!
