The human genome is a rich, complex record of migration, encounters, and inheritance written over thousands of millennia. In this month of love, amid the exchange of flowers and cards, genomic ...

Previous models of self-incompatibility accounted for only one-to-one interactions between male and female-determinant proteins. The new model allows for a more general network of interactions, where ...

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants ...

New research suggests a genetic dynamic that may have contributed to Neanderthals' extinction. Neanderthal-Museum, Mettmann CC BY-SA 4.0 via Wikimedia Commons Did interbreeding between humans and ...

Self-incompatibility (SI) is a sophisticated reproductive strategy that prevents self-fertilisation and maintains genetic variability in flowering plants. This mechanism involves highly specific ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

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 ...

Modern humans may indeed have wiped out Neanderthals – but not through war or murder alone. A new study suggests that when the two species interbred, a slow-acting genetic incompatibility increased ...

Plants, with their unique immune systems, sometimes launch 'autoimmune responses' by mistakenly identifying their own protein structures as pathogens. In particular, 'hybrid necrosis,' a phenomenon ...

An analysis of the genomes of hybrids of distinct swordtail fish species uncovered a lethal incompatibility between certain combinations of nuclear and mitochondrial genes that encode subunits of ...
