Y and W sex chroms are enigmatic. Compared to the rest of the genome, they show distinct structure and diversity, and are notoriously difficult to assemble. Work led by @mdalikova.bsky.social investigates these patterns for the W chromosome of silkworm, Bombyx mori www.biorxiv.org/content/10.6...

Wrong but useful: Bombyx silkworm W chromosome assemblies are flawed but still capture strongly reduced diversity of repetitive DNA

Degenerate sex chromosomes ( e.g., the Y or W) remain among the most difficult regions of eukaryotic genomes to assemble because they are highly repetitive and structurally complex. While many recent ...
