Team identifies new 'social' chromosome in the red fire ant

Researchers have discovered a social chromosome in the highly invasive fire ant that helps to explain why some colonies allow for more than one queen ant, and could offer new solutions for dealing with this pest.

Supergene research solves the mystery of tiny ant queens

An ant colony is sustained through complex social dynamics, with each member—the queen, males and workers (sterile females)—contributing to the greater community. Some species add complexity to this dynamic with the addition ...

The long and short of a supergene for efficient pollination

Scientists have solved the century-old mystery of a supergene that causes efficient cross-pollination in flowers. The results show that sequence length variation at the DNA level is important for the evolution of two forms ...

Supergenes make bizarre traits in plants and animals possible

Within the same species of butterfly many different wing patterns can occur. How is this possible? According to researchers Ben Wielstra and Emma Berdan, of the Institute of Biology Leiden (IBL), the answer lies within supergenes. ...

Study shows how a single gene drives aggression in wild songbird

A new study shows how differentiation of a single gene changes behavior in a wild songbird, determining whether the white-throated sparrow displays more, or less, aggression. The Proceedings of the National Academy of Sciences ...

A selfish gene makes mice into migrants

House mice carrying a specific selfish supergene move from one population to another much more frequently than their peers. This finding from a University of Zurich study shows for the first time that a gene of this type ...
