A new study presents an evolutionary-biophysical model that sheds new light on the evolution of the collaborative non-self recognition self-incompatibility, a genetic mechanism in plants that prevents ...

For more than half a century, the molecular machinery that keeps sugar beet from fertilizing itself has remained one of plant ...

Repetitive DNA and the D1 protein help matching fruit fly chromosomes recognize one another before eggs form.

Stanford researchers have gained new insights into how the rise of reproductive barriers between organisms creates new species and drives the incredible diversification of life on Earth. One major way ...

Justin Havird, Erik Iverson and their colleagues have identified genes involved in hybrid incompatibility in swordtail fishes. The sheepshead swordtail fish (Xiphophorus birchmanni). Photo credit: Dan ...

Reproductive isolation in Drosophila involves a suite of genetic mechanisms that operate at sequential stages to prevent gene flow and facilitate speciation. Premating barriers arise through ...
