DOI: 10.1016/j.cub.2019.11.032
Abstract: Supergenes, clusters of tightly linked genes, play a key role in the evolution of complex adaptive variation [1, 2]. Although supergenes have been identified in many species, we lack an understanding of their origin, evolution,… read more here.

DOI: 10.1038/s41598-020-67999-z
Abstract: Colony social organization of multiple Solenopsis fire ant species is determined by a supergene with two haplotypes SB and Sb, which are similar to X/Y sex chromosomes. The ancestral monogyne (single-queen) social form has been… read more here.

DOI: 10.1093/molbev/msac035
Abstract: Abstract Supergenes are nonrecombining genomic regions ensuring the coinheritance of multiple, coadapted genes. Despite the importance of supergenes in adaptation, little is known on how they originate. A classic example of supergene is the S… read more here.

DOI: 10.1111/mec.16196
Abstract: Supergenes, regions of the genome with suppressed recombination between sets of functional mutations, contribute to the evolution of complex phenotypes in diverse systems. Excluding sex chromosomes, most supergenes discovered so far appear to be young,… read more here.

DOI: 10.1111/mec.16821
Abstract: Supergenes are clusters of linked loci that control complex phenotypes, such as alternative forms of social organization in ants. Explaining the long‐term maintenance of supergenes is challenging, particularly when the derived haplotype lacks homozygous lethality… read more here.

DOI: 10.7554/elife.79387
Abstract: In white throated sparrows, two alternative morphs differing in plumage and behavior segregate with a large chromosomal rearrangement. As with sex chromosomes such as the mammalian Y, the rearranged version of chromosome two (ZAL2m) is… read more here.
