Epigenetic twists: hundreds of inherited DNA patterns defy Mendelian genetics
TL;DR Summary
Mouse study reveals inherited DNA methylation patterns that break Mendel’s rules, identifying 522 non-sex-chromosome cases across three generations (~7%), plus emergent patterns and probable paramutation, suggesting inheritance can be shaped by epigenetic marks beyond DNA sequence and may influence trait transmission and disease risk.
