This is book is as comprehensive and thorough as a good introduction to genetics gets.
What the authors have accomplished (obviously after many editions) is very impressive. The book reads like a scientific saga, and I'm totally gobsmacked by the growth of the field since Mendel and the technological innovations made relatively recently in whole genome sequencing and next gen. sequencing. This book doesn't miss a thing. What's more, it does an excellent job at elucidating the thought processes that go behind the formation of good hypotheses by using real, groundbreaking experiments from the past 100 years that have propelled the field forward.
The writing is effective, the summaries at the end of each important paragraph are helpful, and the occasional delves into the mind of good scientist are invaluable.
