Whole Genome Sequencing Reveals How Plasticity and Genetic Differentiation Underlie Sympatric Morphs of Arctic Charr Salmonids have a remarkable ability to form sympatric morphs after postglacial colonisation of freshwater lakes. These morphs often differ in morphology, feeding and spawning behaviour. Here, we expl....

Talk:Linkage disequilibrium - Wikipedia

Just want to share this wild revision history of the Wikipedia page on Linkage Disequilibrium where Felsenstein himself debated people on the correct use of notations & definitions.

After 100 years of #popgen people does not seem to be totally agree on what LD is?

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...

The secret to what makes colours pop on dazzling songbirds Hidden layers of colour in the plumage of tanagers and some other songbirds explain what makes them so eye-catching

Painters often prime a canvas with a layer of white to make it smoother, stronger and to enhance the colours they will later layer on, but it seems this is a mechanism that birds were using long before humans picked up paintbrushes.
