ANOTHER direct challenge has been posed to one of the cornerstones of biology, Mendel’s laws of inheritance. Mendel’s laws underlie almost all of genetics. They state, for example, that it is the ...
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 ...
