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 ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring.

Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced ...

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 ...

The Finnish population has provided investigators with a rare opportunity. Most Finns descend from a small, so-called founder population of individuals, and people have primarily reproduced with ...

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

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

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

Although schwannomatosis is a genetic condition, the inheritance patterns for this disorder are complex and much less clear than for both NF1 and NF2. Some cases of schwannomatosis are familial, with ...
