GENES ARE WHO YOU ARE!

​NOT YOUR JEANS

Genetics is the study of genes. Our genes carry information that gets passed from one generation to the next.

Ex. Genes are why one child has blonde hair like their mother and their sibling having brown hair like their father.

​Genes are sections of DNA that are found inside every human cell.

​​DNA

​DNA is tightly wrapped together in structures called chromosomes.

​​Chromosomes

​DNA is made of 4 chemicals that form pairs in different combinations. Combinations create codes for different genes.

Each person has about 20,000 genes.

​​Combinations
