Great perspective by @philipcball.bsky.social.
Elementary genetics teaching (HS/college) focuses on Mendelian traits (single gene => single trait). However, it is now clear that polygenicity and pleiotropy are the norm. Curriculum must change accordingly.

In our recent preprint, we explored why psychiatric disorders — and, more broadly, brain-related traits involving the central nervous system — appear to have unusual genetic architectures.
