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 ...

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 ...

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.

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 ...

The genetic bases of the seven pairs of contrasting traits in the garden pea that were described by the ‘father of genetics’, Gregor Mendel, have long puzzled scientists. The discovery of the genetic ...
