Genes are made of DNA. They give instructions for making proteins, which decide how we look and what traits we have.
Eye Color: At least 6 genes play a role in deciding our eye color. Two important ones are called OCA2 and HERC2. Because of these genes, eye colors can vary. Brown is the most common color, found in 79% of people worldwide, but you can also have blue eyes.
Height: There are over 700 different genes that can affect how tall someone is. About 80% of a person’s height is passed down from parents to children. Many genes work together to determine how tall we grow.
By understanding these genetic factors, we can see why people are so different from each other.
