How much of our lifespan is written in our genes, and how much is sitting on our plates? A new analysis suggests that while ...

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 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 ...

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

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

Genetics can play a role in a person's odds for Alzheimer's disease, and new research suggests differences in that risk are based on which parent had the illness. In a study of 4,400 people still ...

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 ...

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, ...

I recently underwent genetic testing to see if I had any mutations that could be associated with an increased cancer risk. When I received my genetic testing kit in the mail, I quickly opened the ...

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 ...
