human genetics/genomics papers assume you understand an enormous amount of details of human genetics, the knowledge of which has been hard-won over a century. I worked in this field for decades, know a ton, and still have to read every sentence in this paper carefully, multiple ttimes, and check various sources to remind myself of technical concepts. There's a reason I switched to working on computing full time- a lot of these state of the art arguments can only be contributed to by people who are, well, state of the art, thick-skinned, and well-funded.
If you’re a layperson wrt genetics, check out ‘The Gene’ by Siddartha Mukherjee - it’s not too dense, interspersed with personal stories he relates to genetics and a great read. His book on cancer is also amazing, ‘Emperor of all maladies’
In my limited experience, these are two of the best non fiction books I’ve read. The author makes these subjects utterly fascinating. If he released a book about watching paint dry, I’d buy it in a heart beat and read it.
