Is it true that DNA methylation patterns can be inherited across generations?
Unclear. Several peer-reviewed and reference sources report that DNA methylation patterns can be transmitted across generations, but each covers only a specific organism, gene, or context (plants, honey bees, rodents, trauma cohorts), and some describe the general mechanism as still debated in mammals. No single source establishes the general claim outright.
