The material is very good and Mukherjee does a good job giving us a history of genetics, keeping our interest for most of the book.

Once you get to the 70s, if you are not familiar with genetics, I would recommend watching a couple YouTube videos on DNA, RNA and gene sequencing. Mukherjee has some excellent diagrams explaining a genes role within an organism, but it does get more technical as the science of the gene explodes in the 70s and continues to grow as each decade passes.

Overall a good read. I would recommend it to someone interested in the history of genetics.
