Meiotic drive against chromosome fusions in butterfly hybrids

Boman, J., Wiklund, C., Vila, R. et al.,  Chromosome Research,  32. 2024.
Species frequently differ in the number and structure of chromosomes they harbor, but individuals that are heterozygous for chromosomal rearrangements may suffer from reduced fitness. Chromosomal rearrangements like fissions and fusions can hence serve as a mechanism for ...

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 ...
