Gregor Mendel described his experiments with pea plants and proved that genes are transmitted in discrete units, with certain ...

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 ...

A monastery garden in the mid-1800s became the birthplace of genetics. Gregor Mendel, a friar, studied pea plants. He ...

The Y chromosome is inherited only through the paternal line. Sons receive their Y chromosome exclusively from their father.

The Finnish population has provided investigators with a rare opportunity. Most Finns descend from a small, so-called founder population of individuals, and people have primarily reproduced with ...

Dear Readers: For most people, finding out that they have come into an inheritance is a positive experience. Not so when that inheritance is early onset familial Alzheimer's disease (eFAD). This type ...

The genotype of an organism is inherited from its parents through the process of reproduction. During sexual reproduction, each parent contributes half of the genetic material to the offspring, ...

How big of a role do our genes play in our lifespan? Quite a bit more than previously thought, a new study suggests.

Some Juneau friends planted holly bushes in their front yard a few years ago. Those bushes grew well, producing dark green leaves with smooth edges. However, during a few winters of heavy snow, deer ...

Neurofibromatosis type 2 is caused by a change in the NF2 gene located on chromosome 22. This gene encodes a protein known as merlin. Mutations in the NF2 gene disrupt the function of merlin, which is ...

Although schwannomatosis is a genetic condition, the inheritance patterns for this disorder are complex and much less clear than for both NF1 and NF2. Some cases of schwannomatosis are familial, with ...
