  1. 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.

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

    Still new things to learn.

  3. 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 years

    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.

  5. 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 plos.io/4bdrwlu

  6. 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 !

  7. Beyond X and Y: #Fish have different methods of sex determination oceanbites.org/beyond-x-and-y-

    Rapid turnover and #evolution of sex-determining regions in Sebastes #rockfishes onlinelibrary.wiley.com/doi/10

    "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."

  8. Nice special issue on sex chromosome evolution onlinelibrary.wiley.com/toc/14
    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:)
