Epigenetic memory is one of the strangest and most consequential features of the genome. Across generations, cells and even ...

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 ...

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.

Indian mustard, one of the world’s most important oilseed crops, has long frustrated breeders trying to exploit hybrid vigor ...

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 ...
