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 ...

Scientists use tools like Punnett squares to predict how traits are passed from parents to offspring. Features like freckles and eye color are examples of these traits. Learn how scientists use plant ...

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 ...
