What determines these antigens?

It’s like deciding what kind of cookie to bring to a party, you choose based on what makes you unique.

Antigens are like those special cookies that show others who you are. But what determines which cookies (or antigens) you have? That depends on your genes, the instructions you got from your parents when you were born.

Think of genes as a recipe book. Every person has their own version of this book, and it tells them how to make different kinds of cookies, or antigens. If your recipe says “add chocolate chips,” you’ll have chocolate chip cookies (or antigens). If someone else’s recipe says “use sprinkles,” they’ll have sprinkle cookies instead.

Sometimes people get a little mix-up in their recipe book, like if one parent has chocolate chips and the other has sprinkles. Then, you might end up with both kinds of cookies!

Imagine your friend has blue eyes because of their recipe book, while you have brown eyes from your recipe. That’s how antigens work too, they’re shaped by what's written in your gene recipe book, making you unique and helping others recognize you!
