Populations occupying heterogeneous environments may evolve locally advantageous traits under divergent selection pressures 1. How different forms of genetic variation contribute to such environmental ...

We learn that we inherit two copies of every gene, one from each of our parents, but the story is a bit more complex. Some parts of the genome may be duplicated, or deleted, in some people. The number ...

A new study challenges the conventional wisdom surrounding genome stability within closely related organisms and sheds new light on the mechanisms underlying extensive genome size variation. Our ...

Human genomes frequently mutate through duplication and deletion, leading to copy number variation. Roughly 10% of protein-coding genes have shown copy number variation, with distinct distributions ...

The evolution of the MUC7 gene, which encodes a saliva protein, was studied by scientists at the University at Buffalo. To capture the gene’s proline-, threonine-, and serine-rich tandem repeat copy ...
