Meiosis: The silk moth and the elephant

Curr Biol. 2024 Mar 11;34(5):R211-R213. doi: 10.1016/j.cub.2024.01.046.ABSTRACTIn most eukaryotes, balanced chromosome segregation at meiosis requires crossovers, but female Bombyx mori lack these structures. Instead, the synaptonemal complex is repurposed to compensate for this absence of crossovers, a remarkable example of exaptation.PMID:38471453 | DOI:10.1016/j.cub.2024.01.046
