The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

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.

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 ...

Every year, millions of newborns undergo routine heel-prick screening, a simple test that can mean the difference between a healthy life and catastrophic disability. Now, breakthroughs in ...
