For more than a century, heredity has been framed through the tidy logic of Mendel’s pea plants: traits pass from parent to ...

A major mouse study found that some inherited traits are passed down through epigenetic changes that break the classic rules ...

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 ...

When we think about genetic inheritance, we usually leap to DNA, the four-letter code containing the instructions for building a living organism. Scientists know that DNA encodes everything from hair ...

Using this system, we can map out the genetics of animals and see what combinations of genes the parents pass on to their calves. This is the key to understanding inheritance. Coat color basics Cattle ...

Mice show that DNA methylation tags can defy Mendel’s inheritance rules by appearing in offspring even when neither parent ...

Bacterial cells are prokaryotic and basic, and carry biomolecules like proteins and DNA encased in a cellular membrane. Cells ...
