Join our online course on Sex Chromosome Evolution (6–10 Oct) with @astridboehne.bsky.social & @idarolti.bsky.social to gain hands-on experience in genomic and transcriptomic analyses. www.physalia-courses.org/courses-work... #SexChromosomes #GenomeEvolution #Transcriptomics #ComparativeGenomics

I'm very happy to share that our paper describing the evolution of sex chromosomes in brown algae is out!🎉 This project was a long journey, but it came together into a nice story 🧬 🌊 Grateful to everyone who helped along the way!

Family photo of the 2025 Workshop of the @treeofsex.bsky.social ! Thanks everyone for attending and see you soon!

Great work by @aruizherrera.bsky.social's lab! Amazing paper and have you see the graphical abstract? Happy reading!

This is insane! The Atlas blue butterfly has 227 pairs of autosomes and four sex chromosomes, the highest recorded chromosome number in non-polyploid Metazoa!!!! See below!🦋

Hot from the press: XX/XY sex determination in Nautilus (unique among cephalopods)!!!! 🐙

The day 2 of the #TreeOfSex annual workshop started with a great talk by @yannguiguen.bsky.social about B chromosomes and their role in sex determination in fish. Next up, Sònia Garcia is giving an update on the works of the Literature team.

Tree of Sex annual workshop started today. It will be two days packed with reproductive biology.

Good to see some of our US-based ToS members at #Evol2025! If you're at the meeting and interested or just curious about the project, say hi to @ajmongue.bsky.social @nicolevalenzuela.bsky.social @ideaspermatheca.bsky.social @emistasis.bsky.social, Mike White or Louise Heitzmann!

Officially (re-)annoucing the Tree of Sex! Read all about it in JEB below!

As work ramps up, we've created a Starter pack to follow members of the consortium. go.bsky.app/QjiXdsc Please comment below to be added!

Hi folks, this is the official Tree of Sex account. We are an open consortium of reproductive scientists with the aim to catalogue reproductive knowledge across Eukaryota. You can be part of it too: treeofsex.sanger.ac.uk

The @treeofsex.bsky.social is working on this! 🤞🏽
