Genetics
Inheritance, variation, mutations, and the ways DNA differences shape biological outcomes.
This topic is part of the long-term MOLBIO taxonomy and is visible now so the learning map stays honest. The hub is live, but the dedicated lesson set is still being built.
Lightweight learning path
Move from molecules into inherited traits
This hub will eventually connect DNA-level concepts to variation, mutations, and trait-level consequences.
