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 ...

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 ...

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

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 ...

The same pathogen can often elicit very different responses from different people. Scientists sought to understand more about ...

The year was 1900. Three European botanists — one Dutch, one German and one Austrian — all reported results from breeding experiments in plants. Each claimed that they had independently discovered ...

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 ...

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 ...

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 ...
