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 ...

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 ...

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 ...

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

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.

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 ...

Genetic factors primarily explain the link between parental and childhood BMI, with maternal obesity impacting birth weight ...

Duchenne muscular dystrophy (DMD) occurs as a result of genetic changes on the X chromosome. If someone has a gene change that can cause DMD, their children may inherit that change. DMD is a ...
