What are the major themes in NVS PGT Science Biology Genetics?

In NVS PGT Science Biology, major themes in Genetics include the structure and function of DNA, the principles of inheritance, and the mechanisms of gene expression. Focus on understanding Mendelian genetics, patterns of inheritance, and genetic variations that arise from mutations. Additionally, explore modern genetic technologies such as CRISPR and genetic engineering, as well as ethical implications surrounding them. Finally, study population genetics and evolutionary mechanisms to grasp how genetic principles apply to broader biological contexts.
