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 ...

A new international study challenges the century‑old dominance of Mendelian genetics, arguing that most traits arise from complex interactions among many genes rather than single gene–trait links.

Scientists found that some inherited traits can bypass the traditional rules of genetics, revealing a surprising new layer of ...

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 ...
