Meiotic drive against chromosome fusions in butterfly hybrids

Jesper Boman, Christer Wiklund, Roger Vila, Niclas Backström,  bioRxiv,  2024.
Species frequently differ in karyotype, but heterokaryotypic individuals may suffer from reduced fitness. Chromosomal rearrangements like fissions and fusions can thus serve as a mechanism for speciation between incipient lineages but their evolution poses a paradox. How does ...
