I treasure this book!
The title of the book accurately reflects the approach Professor Ringo took to write a book on Modern Genetics.
Unlike other highly commercial Genetics/Genomics books, Prof. Ringo's book is intended to guide the reader in a logical, organized, didactic, clear, and entertaining way thru the tortuous complexities of modern Genetics and Genomics.
I am finding it extremely valuable as a companion to the more technical BioInformatics studies which I am independently pursuing (with the help of Coursera BioInformatics online classes)
(There are other excellent texts which I think are however too cluttered and dense for use as an efficient and reliable reference)
