I bought this book, because a friend of mine once mentioned it, and when I later stumbled on it I simply had to buy it. It amazed me to find such a relatively huge amount of "knowledge" in a "comic book", or in a book for that matter!! Having some insights in genetics I was surprised to see that it didn't leave any wide gaps or ironically didn't fill them with useless garbage. However, do not go to such lengths as believing to have read everything needed to make a clone of your dog, because even though it brings about information, bare in mind that information can come in many forms: Morse code, (-*-DNA-*-) etc. but also detailed information. Regard this masterpiece as a very-well written and informative summary of how BASIC genetics work and not a "detailed" textbook. Call it a guide....a cartoon guide.....to genetics.
I gave it a mere 4 stars, because I like colors (Couldn't find them....!). But then again, perhaps I am colorblind...........No hold on, let me take a look at my X-Cromosome, yes I see, sure enough, It hasn't mutated... :)
