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

In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Most people with ALS don’t have a family history of it. Still, some cases of ALS are linked to inheriting specific gene mutations. Even nonfamilial cases can be linked to sporadic gene mutations that ...

Parents pass their genes down to their kids, with a child inheriting about 50% of their genome from each parent. But there is another kind of genetic code known as the epigenome that can also be ...

From your eye color to your health risks, genetic inheritance plays a powerful role in who you are. Understanding dominant, recessive, and X-linked traits can help you make sense of family patterns ...

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 ...

Traditionally, differences among individuals have been divided into genetic and environmental causes. However, both types of variation can underlie regulatory changes in gene expression — that is, ...

Some traits come only from your mother, from mitochondrial DNA to intelligence and inherited health risks. The post Traits ...

The question of how the effects of genetic variants combine to produce continuous traits, such as height and blood pressure, as well as complex diseases, including diabetes and Alzheimer’s disease, ...

Chronic kidney disease (CKD) is a public health challenge that affects more than 800 million people worldwide. 1 CKD can be caused by a variety of disease processes. Many causes are difficult to ...
