I used the Kaplan lectures notes for this. I felt it gave me a very solid review. This book has bio chem, mol bio, and genetics together. There is a lot of overlap between Genetics and Mol bio.
Many of the genetics topics are found in the genetics disorders section of BRS Path. Other than that, I'd know basic mendelian calculations, Hardy-weinberg, how meisosis and cross over works, and how things like robertsonian translations work. Not sure what review text covers these, sorry 🙁
