Hemophilia is a bleeding disorder that can affect the blood’s ability to clot properly. In most cases, people inherit the gene variations for hemophilia in an X-linked recessive inheritance pattern.

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

The genetic bases of the seven pairs of contrasting traits in the garden pea that were described by the ‘father of genetics’, Gregor Mendel, have long puzzled scientists. The discovery of the genetic ...

Retinitis pigmentosa (RP) is an eye condition that can be genetic. In this way, people usually need to inherit two copies of a genetic variation that causes RP, one coming from each parent. RP may ...

Rare genetic traits are features that are uncommon within the general population. They can lead to different observable features or to rare physical abilities. Rare genetic traits are typically ...

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 ...

Obesity is a complex disorder that is dependent on environmental and genetic factors. Severe obesity, which is otherwise known as class III obesity, is a chronic condition that increases the risk of ...

SYDNEY, Feb. 20 (Xinhua) -- Researchers in Australia have modeled how genes can influence a child's body mass index (BMI) over time, potentially shaping the risk of heart disease or type 2 diabetes ...
