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

Any user of ANGSD on here has a trick to obtain the exact same set of sites per population when making subsets of individuals?
I can never retrieve the same sets and it is extremely annoying! This is basic popgen stuff.
The bare minimum would be to output missing data for sites impossible to analyze in this pop, so that output files can align between analyses.
(I use -sites without any filters)

#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

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:

https://www.biorxiv.org/content/10.1101/2021.07.13.452277v2

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.

Hello Mastodon people,

I wanted to mention that I have a new preprint out on bioRxiv:

https://www.biorxiv.org/content/10.1101/2024.01.16.575829v1

I think it could be really useful for people interested in the consequences of #Recombination on #Genome #Evolution, but more generally in interpreting DFEs, positive selection and dN/dS.

I will take the time to make a thread once the final paper is published (I hope it will).

For those who will take the time to read it, don't hesitate to give me feedback 😊

Who will be going to PopGroup 57 in St. Andrews next week? I was planning on using BlueSky, but without hashtags such as #PGG57 #Evolution #PopGen, I'm not sure how it will work?

Two new student-led #evobio #popgen #ecoevo #mathonco preprints!

1. Preventing Evolutionary Rescue in Cancer

2. Selective sweep probabilities in spatially expanding populations

Both tick all my boxes for exciting research:
✅ Interesting theoretical results
✅ Sophisticated mathematics
✅ Important biological implications
