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

A mouse study shows that about 7% of inherited DNA methylation patterns follow non-Mendelian rules, revealing unexpected ...

Researchers have identified inherited genetic variants that may predict the loss of one copy of a woman's two X chromosomes as she ages, a phenomenon known as mosaic loss of chromosome X, or mLOX.

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

The blueprint of who we are begins with the genes passed down from our parents. While these inherited traits give us our eye color and height, they can also contain instructions that increase our risk ...

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 ...

The medical literature overwhelmingly characterizes the Druze as what researchers call a “genetic isolate,” meaning that ...

Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced ...

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 ...

Research on Tourette’s indicates that the condition is strongly influenced by inherited genetic factors, with environmental factors also contributing to its development. Tourette syndrome is a ...
