Genetics — Start Here

Dive into how traits are inherited, how multiple genes and environment shape complex conditions, and how life experiences can leave epigenetic marks that influence gene expression.

Fun Fact — “Snatiation”: Some people sneeze after they feel full. This heritable reflex (sneeze + satiation) likely involves autonomic stretch-receptor pathways and hypothalamic signaling.

Yes, your genes can literally make you sneeze when dinner hits the “I’m done” switch.
