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 ...

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 ...

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

These resources provide an overview to how the basic principles of inheritance were studied and elucidated by Gregor Mendel. Basic linkage analysis is also described to serve as a foundation for more ...

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 ...
