Two genes explain variation in colour and behaviour in the wall lizard

Two genes explain variation in colour and behaviour in the wall lizard

Press Releases   •   Mar 01, 2019 09:24 GMT

How are reptiles capable of generating such a diversity of bright colors? And how is it possible that within a single population of the same species, different individuals exhibit strikingly different coloration patterns? A team of scientists reveal two genes implicated in yellow to red pigmentation in reptiles, and demonstrate that these “pigmentation genes” also affect behaviour and other traits

The critically endangered Grauer’s gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations. These conclusions were reached by an international team of researchers who sequenced eleven genomes from eastern gorilla specimens collected up to 100 years ago, and compared these with genomes from present-day individuals. Results are published in Current Biology.

During the Triassic period mammal-like reptiles called therapsids co-existed with ancestors to dinosaurs, crocodiles, mammals, pterosaurs, turtles, frogs, and lizards. Researchers at Uppsala University in Sweden, together with colleagues in Poland, have discovered fossils from a new genus of gigantic dicynodont. The new species Lisowicia bojani is described in the journal Science.

Unravelling the genetics of fungal fratricide

Unravelling the genetics of fungal fratricide

Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers at Uppsala University have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings.
