An easy read. Mukherjee delved into the personalities of various scientists involved in studies of the gene, which assisted my understanding of the development of their theories. The use of his own family history grounded me in the application of these theories. His examples; his descriptions; everything was so lucid. I found his discussion of gender and gender identity very interesting. The penultimate section (Post Genome) raised all kinds of red flags as to the future of humanity.
Anybody with even minimal curiosity about genetics should read this book.
