Scientists found that some inherited traits can bypass the traditional rules of genetics, revealing a surprising new layer of ...

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 ...

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 ...

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 ...

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

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 ...

Researchers have identified inherited genetic variants that may predict the loss of one copy of a woman's two X chromosomes as she ages, a phenomenon known as mosaic loss of chromosome X, or mLOX.

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 ...

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 ...
