Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

For more than a century, heredity has been framed through the tidy logic of Mendel’s pea plants: traits pass from parent to ...

A major mouse study found that some inherited traits are passed down through epigenetic changes that break the classic rules ...

Mice show that DNA methylation tags can defy Mendel’s inheritance rules by appearing in offspring even when neither parent ...

The findings reveal the biology behind segregation distortion, a phenomenon in which genes sway inheritance in their favor to beat the standard 50/50 odds predicted by Mendelian genetics. The team ...
