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

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

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

A new study suggests that the long-standing Mendelian view of genetics has some blind spots.

Genetics influences who of us are more likely to experience a relationship breakdown, and who are more likely to remain ...

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 ...

In a recent study published in Nature Genetics, researchers created a comprehensive atlas to elucidate the combined impacts of genetic inheritance and environmental exposures on the human immune ...

Some variation is the result of differences in the surroundings, or what an individual does. This is called environmental variation. Humans, dogs and goldfish are examples of species. Different ...
