Okuno et al. assemble male genomes for three spiny rat species, tracing Y chromosome loss and gene translocation. Authors show that segmental duplications and rearrangements enabled preservation of Y-linked genes on the X.

Men can lose their Y chromosome in some cells and it makes them more prone to illness?!?
Still new things to learn.

Let me tell you 'bout the birds and the bees and the octopuses:

#Octopuses have some of the oldest known #sexChromosomes
New research at the UO shows they’ve been using one that’s been around for 480 million yearshttps://www.eurekalert.org/news-releases/1072206 #science #evolution #chromosomes #genome #sexDetermination #cephalopods

A nearly gapless #genome sequence of the #echidna, an egg-laying mammal with multiple #sexChromosomes, helps researchers to track genomic reorganization events that gave rise to a highly unusual #sexDetermination system.
related to the system of the #platypus which was the cover story in my book "Der Kuss des Schnabeltiers" / "The birds, the bees, and the platypuses." 15 years later I can't remember how that worked but I loved the story.

Sex- and cell-type-specific regulation on #SexChromosomes. @kweiosis &co take advantage the young sex chromosomes of #Drosophila miranda to explore how ex-autosomes acquire sex chromosome-specific regulatory programs #PLOSBiology https://plos.io/4bdrwlu

Sex Unfolded Jacques Monod Conference. Third Edition in incredibly sunny Roscoff. Already 1 week ago. Thanks to all the participants! Many new ideas for the #evolutionofsex #recombination, #SexChromosomes #asexuality #evobio #popgen. 4th edition in 5 years by @KarineDoninck and Sylvain Glémin !

Beyond X and Y: #Fish have different methods of sex determination https://oceanbites.org/beyond-x-and-y-fish-have-different-methods-of-sex-determination/
Rapid turnover and #evolution of sex-determining regions in Sebastes #rockfishes https://onlinelibrary.wiley.com/doi/10.1111/mec.17090
"Some fish even change sex partway through their adult life, based on size or age! Closely related species of fish often have different #SexChromosomes or lack clear sex #chromosomes altogether, indicating that #SexDetermination evolves quickly and is highly variable."

Very nice overview by @jfmclaughlin92 et al of the complexity of concepts of "sex" in animals, at both #genetic and #phenotypic levels. #EvolutionaryBiology #SexChromosomes #ecoevo #zoology

Nice special issue on sex chromosome evolution https://onlinelibrary.wiley.com/toc/14209101/2022/35/12
including "X chromosomes show relaxed selection and complete somatic dosage compensation across Timema stick insect species" by Parker et al @KamilSJaron (other authors not on :mastodon:)
