Do girls look like mom or dad?

Published in Genetics 1 min read

It's impossible to predict whether a girl will look more like her mom or dad.

Here's why: Girls inherit one X chromosome from their mother and one X chromosome from their father. This means they receive genetic material from both parents, making their appearance a combination of traits from both sides of the family.

Think of it like mixing paint: you can't predict the exact shade of blue you'll get when you mix a specific amount of your parents' colors. Genetics is far more complex than just dominant and recessive traits determining everything. Many genes contribute to a single characteristic, and these genes can interact in unpredictable ways. Furthermore, environmental factors also play a role in shaping a person's appearance.

Therefore, while certain features might seem more dominant from one parent, it's the combination of both parents' genetic contributions that ultimately shapes a girl's appearance.
