Genes are often called "blueprints" for our bodies because they hold the instructions for creating and keeping everything we need to live. Here’s why this comparison works:
Instructions: Think of a blueprint as a guide for building a structure. Genes give us detailed information to make proteins that are super important for how our bodies work. Each gene has its own code that tells the body how to create different proteins.
Variability: There are different versions of genes, known as alleles. These can cause differences in traits. For example, you might get a gene for brown eyes from one parent and a gene for blue eyes from the other. It's like how different architects might create unique designs for the same building.
Expression: Not every gene is active all the time. They can be turned on or off based on different factors, much like how certain parts of a blueprint are used during building. This selective gene expression affects how our traits develop.
In short, genes are the blueprints for our physical traits and body functions. They play a big role in shaping who we are!
