Selfish B chromosomes can spread via super- #Mendelian transmission, but this can be limited by forces like drag. This study shows that jewel #wasp PSR #chromosome spreads via strong paternal drive, hidden female meiotic drag, and restriction to a single copy @plosbiology.org 🧪 plos.io/4r0cJCE

Population-scale long-read datasets, involving sequencing and de novo assembly of multiple individuals within a species, are better at capturing the full spectrum of structural variants, but such datasets are rare outside of humans www.science.org/doi/10.1126/... #biodiversity #genomics

How do new centromeres evolve while staying compatible with the division machinery? Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore. 👉 doi.org/10.1038/s41586-025-09779-1

🌺New paper out in @annbot.bsky.social, addressing the morphological disparity of aggregated pollen in mimosoid plants! We found that disparification in the studied groups was mainly driven by morphological innovation and lineage-specific history, not by habitat. academic.oup.com/aob/article-...
