Learn all about how your DNA makes you who you are--an awesome, unique individual--in this fun and simple illustrated guide! Did you know your sense of purpose is determined by your genes? And that DNA determines your reaction to poison ivy, and maybe even your sex drive? In DNA Is You!, the author behind Beatrice the Biologist uses her trademark humor to break down the ins and outs of DNA to give you the low-down on each trait, one by one. She provides the answers to questions like: how dependent are traits on your parents' genes? Are they based on mutations or influenced by the environment? What kind of studies have been performed on genetics, and what have they discovered? Home DNA tests are more popular than ever, and DNA Is You! takes a look at the weird and wild scientific factors that can change your genes--like that dimples are dominant, how someone gets two different eye colors, and which genes determine whether or not you'll need glasses. Learn more about how you got to be who you are with DNA Is You! and understand yourself--and your family--a little bit better!
