How Does DNA, Chromosomes, Genes, and Traits: An Intro to Heredity Work?

DNA is like a recipe book that tells your body how to grow and work, and it’s passed down from parents to kids.

DNA lives inside chromosomes, which are like tiny books in your cells. Each cell has many of these little books, and they help your body know what to do.

A gene is a single page in that recipe book, it tells your body how to make something specific, like eye color or hair type. You get one copy of each gene from your mom and one from your dad.

When the genes work together, they create traits, things you can see or feel, like blue eyes or curly hair. Sometimes a gene from mom is stronger than one from dad, just like how chocolate ice cream might win out over vanilla in a battle for the last scoop.

Your body uses DNA to build proteins, which are like tiny workers that help your cells do their jobs. If the recipe (gene) says “blue eyes,” the worker makes sure your eyes end up blue!

Each person has 46 chromosomes, 23 from mom and 23 from dad. These come together like puzzle pieces to make all the traits you have.

So, when you grow up, you might look a lot like your parents, or maybe like one more than the other! It’s all in the genes. DNA is like a recipe book that tells your body how to grow and work, and it’s passed down from parents to kids.
