Abstract excerpt
Chromosomal inversions can contribute to adaptive speciation by linking coadapted alleles. By querying 1375 genomes of the species-rich Malawi cichlid fish radiation, we discovered five large inversions segregating in the benthic subradiation that each suppress recombination over more than half a chromosome. Two inversions were transferred from deepwater pelagic Diplotaxodon through admixture, whereas the others...
