The cool part? We could experimentally recapitulate these transitions: from hybridogenesis to parthenogenesis, and from a diploid parthenogenetic lineage to a triploid one.

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.

How do alternative reproductive modes arise? In this @pnas.org paper, we show that hybridogenesis -where a haploid set of chromosomes is transmitted clonally across generations- acted as an intermediate step between sexual and asexual reproduction in stick insects. doi.org/10.1073/pnas...

New paper with @vsudbrack.bsky.social. Using pop gen modelling, we show that partial selfing makes selection on tandem repeats more efficient, reducing the associated load across different scenarios. Thanks to @snsf.ch @dee-unil.bsky.social @fbm-unil.bsky.social ! www.nature.com/articles/s41...

Are stick insects unique in their ability to transition to parthenogenesis? Our new review in @journal-evo.bsky.social covers intraspecific and hybrid origins, cytological mechanisms, and co-occurence of female-only and sexual populations, with comparisons to other taxa. doi.org/10.1093/evol...

Abstract. Female-producing parthenogenesis is widespread in stick insects. It ranges from rare in sexual species to facultative or obligate, the latter som

Fair point and important concern -it definitely works better once the microphone makes it to you!
