Regular readers of this blog will be well aware that we are currently in the middle of a technology-driven revolution in genetics, which promises both advances in our understanding of human biology and profound social transformation. As we move into the genomic era, developing familiarity with the basic concepts of genetics - so-called genetic literacy - will be increasingly important.The goal of Mark Henderson's 50 Genetics Ideas You Really Need to Know is thus ambitious but timely: to distill the complexity of genetics into a series of digestible bite-sized chunks suitable for public consumption. Each of the Ideas in the book - which range from selfish genes to genetic genealogy to designer babies - is condensed into just four pages, along with a single statement containing the basic message of the section (e.g. for the selfish genes section: "Genes look selfish, but people needn't be"), short vignettes highlighting particular sub-topics of interest, and relevant quotes drawn from a wide variety of sources.
Henderson's coverage of controversial topics is admirably well-balanced where balance is appropriate (a particularly good example being the section on genes and insurance, in which he goes well beyond the standard "genetic discrimination is bad" boilerplate), but he doesn't hold back from dismissing unscientific views: creationists are singled out for criticism in chapter 1, while the alarmist claims of anti-GM activists are dealt with suitably in the section on GM crops.
Given the tight format there are inevitable sins of omission - the polymerase chain reaction, the workhorse of modern molecular biology, is squeezed briefly into chapter 31 (genetic fingerprinting) rather than taking its rightful place in the introductory chapters; and there is no mention of second-generation DNA sequencing in the later chapters covering "the new genetics" - but overall Henderson does an impressive job of spanning the field. Beginning with the history of genetics and finishing with the most recent advances (such as the new-found importance of copy number variation and RNA-based gene regulation), the book takes numerous detours through the more interesting scientific, ethical, philosophical and technological issues around the study of DNA.
This book is not designed to serve as a comprehensive reference text, but rather to engage and inform a broad audience - and it serves this role admirably. Those just starting out on the road to genetic literacy will find it easy to dip in and out of the chapters, unearthing nuggets of dinner party conversation gold; for those interested in exploring further the book provides a solid foundation for building a deeper understanding of the field.
The appeal of the book also extends beyond genetics rookies: I certainly stumbled across several intriguing factoids from areas of genetics outside my specialty, and Henderson's ability to encapsulate a complex concept or argument in a single paragraph will provide useful fodder for anyone involved in communicating genetics to a wider audience.
50 Genetics Ideas You Really Need to Know is an engaging read that fills an important niche; I give it 3.5 nucleotides out of 4.

Love the nucleotide rating system! And will be on the look-out for the book. Thanks for the review.

What can I do with half a thymine?? Reminds me of Martini in "Cuckoo's Nest" breaking a cigarette in half, and saying "I bet a nickel".

You could add "U" and bring it up to the semi-standard 5-[icon] rating system.

Thanks for the review, Daniel. Much appreciated. I'll be blogging on the Times debate at Cheltenham tomorrow -- Kari Stefansson vs Helen Wallace should be great fun!

Just got this book delivered to my house last week. I will add some comments once I am done reading - so far it's very appealing and engaging.

Daniel, I couldn't agree more with your review. I'm a complete neophyte and recently reviewed 50 Genetic Ideas in glowing terms. In fact, I'm taking five of his fifty ideas and am pursuing them further (in my own slow time).
