Persistence of neutral polymorphisms in Lake Victoria cichlid fish.

Proceedings of the National Academy of Sciences of the United States of America - 24 Nov 1998

Nagl S, Tichy H, Mayer W E, Takahata N, Klein J

Abstract excerpt

Phylogenetic trees for groups of closely related species often have different topologies, depending on the genes used. One explanation for the discordant topologies is the persistence of polymorphisms through the speciation phase, followed by differential fixation of alleles in the resulting species. The existence of transspecies polymorphisms has been documented for alleles maintained by balancing selection but...
