What are punnett squares?

A punnett square is like a recipe for mixing traits from two parents to see what their kids might look like.

Imagine you have a box, this is your punnett square, and it has spaces inside where you can mix flavors, just like mixing genes. Let’s say one parent has chocolate chips and the other has vanilla beans. When they mix, the kids could get chocolate, vanilla, or even both in one cookie!

Think of each parent as having two gene choices, kind of like choosing between two kinds of ice cream scoops. We write these on the sides of the square.

Then, we put them together inside the box to see all the possible combinations the kids could have, just like trying every flavor combo in the cookie jar!

If one parent has brown eyes (because their genes are BB) and the other has blue eyes (bb), the punnett square helps show that all of their kids will have brown eyes, because brown is stronger than blue.

It's like having a chocolate chip cookie, even if you mix in a little vanilla, the chocolate still shines through!
