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 ...

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 ...

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 ...

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 ...

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.

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 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 ...

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 ...
