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 ...

Researchers at Johns Hopkins University and Texas A&M University have documented at least 522 autosomal sites where DNA ...

Research on Tourette’s indicates that the condition is strongly influenced by inherited genetic factors, with environmental factors also contributing to its development. Tourette syndrome is a ...

The blueprint of who we are begins with the genes passed down from our parents. While these inherited traits give us our eye color and height, they can also contain instructions that increase our risk ...

Cancer is caused by genetic changes that occur in our cells over time. There are two main types of changes, namely somatic mutations, which are alterations in the DNA sequence, and copy number ...

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 ...

Identifying the mutations that underly unusual sleep traits can provide insights into the biology of sleep and circadian function in humans. In the 1990s, a woman approached sleep neurologist ...
