Need study strategies to link Mendelian genetics with epigenetics and GWAS

[Ryan.M]

I'm a first-year biology student who is struggling to connect the dots between the core genetics fundamentals we're learning, like Mendelian inheritance and DNA replication, and the more complex modern topics like epigenetics and genome-wide association studies. I understand the individual concepts in lectures, but I'm having trouble building a cohesive mental framework that links classical genetics with molecular biology. For students or educators who have a solid grasp of the subject, what study strategies or resources helped you see the bigger picture? Are there specific diagrams, analogies, or foundational principles you focused on mastering first that made everything else fall into place more easily?
