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 ...

A new study suggests that the long-standing Mendelian view of genetics has some blind spots.

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

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 ...

Gregor Johann Mendel’s experiments on pea plants in the mid-19th century established the fundamental principles of heredity by demonstrating that traits are transmitted as discrete “units” rather than ...

Data from a series of randomized trials in the United States suggests that if teachers move genetics instruction toward more complex genomics concepts, they can help students have a more ...

Genetic inheritance may sound straightforward: One gene causes one trait or a specific illness. When doctors use genetics, it’s usually to try to identify a disease-causing gene to help guide ...

From eye color to dimples, the traits that make us unique are rooted in the fascinating science of genetics. Our genes, inherited from both parents, interact in complex ways to determine our physical ...
