The cool part? We could experimentally recapitulate these transitions: from hybridogenesis to parthenogenesis, and from a diploid parthenogenetic lineage to a triploid one.
Interested in the molecular mechanisms and evolution of atypical reproductive modes ? Since 2025, we are running a (bi)-monthly online series. You can join us to watch or present!

Today we had an interesting talk on achiasmatic meiosis in the holocentric plant species Rhynchospora tenuis by @amarques.bsky.social
In the incoming weeks/months, we will have talks about atypical reproductive modes in orthopteran and nematods!
We used haplotype-resolved phylogenies to reconstruct the history of transitions between reproductive modes. All hybrids are monophyletic, with asexual lineages nested within hybridogenetic ones. The transition to asexual reproduction subsequently gave rise to two triploid lineages.
