Do you ever wonder why you look the way you do? This is because of DNA and genetics. These are just fancy words for traits, or what you get from your parents! Let's learn more!

What is DNA? DNA is Deoxyribonucleic Acid. It's the molecule that helps you look the way you do. I understand that you don't understand!

DNA is found in all people,animals, and plants. Inside of the middle control center of the cell (we have millions of them)

,or nucleus, there's a hard wall. It has protein and DNA on it. They look just like tiny circles.

You can think of DNA as a spiral. The scintific name is a double helix,but spiral is alot easier to remember. It has all your genes in it

Brown hair, brown eyes, caramel colored skin, straight hair. All depends on your genes. If you had a different mommy or daddy than you do now, you'd look completely different.

Dominant and recessive traits have to do with genes. If your mom holds 50% of your punnett square and your dad holds 50%, then you have an equal chance of looking like either of your parents.

Dominant means stronger than the other. If your mom holds 25% of your punnett square, and your dad holds 75%, you will look like your dad.

A punnett

square shows which traits are dominant and recessive. It can be used by biologists to see what a baby will look like.

The sqare has 4 letters outside of it. One on top of each of the 2 boxes, and one next to each of the 4. 2 of these are uppercase.

The 2 sides represent your parents.You put 1 oe from the top next to one on the sides. So B represents black and b represents brown. Pretty simple, right?
