#popgen — Public Fediverse posts

Biello et al. present the first whole-genome analysis of Mediterranean fin whales, showing that although these form a distinct genetic cluster, they are not fully isolated from North Atlantic populations.

I gave a PopGen Vienna seminar last week. I was impressed by the quality and depth of the discussions I had the all day with all the students of the program. Thank you very much. I learned so much from you, far more than I was able to help you with my limited advice #PopGen https://youtu.be/kAEsLuuLuq0?si=LUlB31eL6MruBcx5

“Here we reframe the inference of coalescence times as a problem of translation between two biological languages: the sparse, observable patterns of mutation along the genome and the unobservable ancestral recombination graph that gave rise to them.” #PopGen #PopulationGenetics

The August cover of Genome Biology and Evolution features the work of Watanabe et al., who uncover the evolutionary history of the Hondo red fox, an endemic subspecies from the Japanese Archipelago.

#PopGen New preprint of the team on the discovery of a very high rate of polymorphic duplication in a marine bivalve.

Imagine looking at the distribution of the allelic coverage fraction at heterozygous calls in an indivdual and getting this distribution 👇 😱😱😱

Four years ago, Jesse Bloom announced the recovery of SARS-CoV-2 sequences and suggested they could come from very early COVID-19 patients. Zach Hensel and I found out that Bloom's claim relied on the deliberate omission of a January 30, 2020 collection date contradicting his narrative. 🧪 #PopGen

Harpy v2.0 is almost across the finish line, and I wrote a lil' post about what linked-read sequencing actually is and how we evaluate the data differently than standard short-read data. It's a quick and easy read (with pictures!), highly recommend 🤓

🚨If you fancy evolutionary genomics, theory, my lab now offers *two* fully-funded #PhD #genomics #popgen #evolution
ℹ️One on sex-asex transitions with Christoph Haag bit.ly/4hp1q1A
ℹ️One on allele-specific expression with Sylvain Glémin bit.ly/4iuKLuQ

In #CEFE lab, Montpellier

Last week, I updated #adegenet on #CRAN. This is an important update as it fixes a memory overflow problem for SNP data that has existed since 2016.

If you use #PopGen packages that import adegenet (e.g. #poppr, #vcfR, or #dartR), then you should update.

3 years (and 2 kids) later, I finally revised the manuscript:

we develop a #popgen method to locate genetic ancestors from tree sequences and apply it to arabidopsis thaliana.

software is ready to be applied to any dataset with Relate trees:

Hi everybody,

I am pleased to share with you my latest work in collaboration with Augustin Cléssin and Nicolas Lartillot:

https://www.biorxiv.org/content/10.1101/2024.06.21.600052v1

GC-biased gene conversion (gBGC) is a process that distorts the segregation of heterozygous AT:GC polymorphisms during meiotic #recombination. This genome-wide non-Mendelian segregation has been shown to be a major source of #genetic load, earning the nickname of “Achille’s heel” of #genomes. (1/2)

Sometimes we miss articles and don't understand how we missed them. I wouldn't normally miss an article by Thomas Wiehe. Fortunately, we always end up doing a more intensive bibliography on an issue we're interested in, and we end up finding the gems we missed. #MustRead #PopGen

Nice new work from Doc @edge on recovering polygenic scores from ancestral recombination graphs.

Scalability vs accuracy.
