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

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 ...

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 ...

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 ...

Around 7,000 years ago, the genetic diversity of human males suddenly dropped across parts of Africa, Europe,and Asia. Scientists studying the DNA, more specifically Y chromosome, and found evidence ...

The unmistakable refreshing snap of a freshly cut cucumber is not an accident of nature but the product of a complex genetic ...

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.

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 ...

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 ...
