Balancing selection alert!! 🧬🧪

New preprint where we try to quantify how likely (or rather, unlikely) it is for balancing selection to maintain stable polymorphism, and how easy (or rather, challenging) it is to identify its signatures in genomes.

We are excited to share our recent work on the surprising robustness of Ancestral Recombination Graph (ARG) inference tools to computational phasing errors, now available on BioRxiv: biorxiv.org/content/10.1....
This work is co-advised by @yundeng.bsky.social and Rasmus Nielsen.

Important heads up! This is crazy
Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.

Ie: it's not us (Samtools team)! Be warned

SINGER, our ARG inference method, is finally published and freely available online:

doi.org/10.1038/s415...

It was a long journey – 16 months from initial submission to acceptance. Is it just me, or has peer review gotten more arduous lately? 4+ rounds of review isn't so unusual these days...
Robust and accurate Bayesian inference of genome-wide genealogies for hundreds of genomes - Nature Genetics
SINGER is a method for creating ancestral recombination graphs to understand the genealogical history of genomes. The method has increased speed, and thus scalability, without sacrificing accuracy.

It's the first human WGS study in Sudan. We uncover one of the strongest selection signals to date, pointing to post-admixture adaptation to malaria in Copts. Huge thanks to all co-authors. @aidaandres.bsky.social @jgarcia-cal.bsky.social @ebosch1972.bsky.social

Outstanding work by @dcsoto.bsky.social @jmuribescr.bsky.social @mydennis.bsky.social (and other collaborators) that massively advances identification of human gene duplicates, with links to important traits and our evolution. So happy to have contributed a bit to this fantastic paper.
