Add Yahoo as a preferred source to see more of our stories on Google. Genetic information in the DNA and modifications, such as DNA methylation, define the epigenetic landscape and phenotype and show ...

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 ...

Parents pass their genes down to their kids, with a child inheriting about 50% of their genome from each parent. But there is another kind of genetic code known as the epigenome that can also be ...

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 ...

Mendel's famous laws of heredity, established over a century ago, may not be as universal as once thought. A recent study on ...

A team of geneticists and animal welfare specialists from the U.K. and one from the U.S. has identified the genetic mutation responsible for a newly discovered cat coat color pattern in Finland. In ...

From your eye color to your health risks, genetic inheritance plays a powerful role in who you are. Understanding dominant, recessive, and X-linked traits can help you make sense of family patterns ...

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 ...

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 ...

For more than a century, heredity has been framed through the tidy logic of Mendel’s pea plants: traits pass from parent to offspring by fixed genetic rules. But a new mouse study suggests that ...
