Many times, scientists embark on a study looking for evidence for a particular hypothesis, and in the process, they come across something totally unexpected and different from their original purpose.

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

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 ...

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 ...

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 ...

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 ...

Our bodily systems are rife with mutations. In fact, your DNA is mutating right now. These errors, and attempts to repair them, are a key to understanding immune function, aging, and even how heart ...
