Check out what Kailey from Luminous Libro said:

"This book explains why some people have curly hair or blonde hair or green eyes. We all get our genes from our parents, and our chromosomes and DNA determine what physical traits we have. Did you know that having freckles is actually a genetic mutation? Some people have mutations that make their bones really strong, or make them really sensitive to bitter tastes.

This is such a fun book! I love the cute illustrations and the hilarious characters. The information is clearly explained step by step in a playful way that makes it memorable. There is a game at the back of the book where you have to choose random physical traits from a bowl and try to draw a person with big ears and a stubby nose and red hair or brown eyes and small mouth and a big chin. The mixture ends up being really funny!"
