An unusual barrier to gene flow: perpetually immature larvae from inter-population crosses in the flour beetle, Tribolium castaneum.

Journal of evolutionary biology - 1 Dec 2011

Drury D W, Jideonwo V N, Ehmke R C, Wade M J

Abstract excerpt

We genetically characterize an unusual hybrid incompatibility phenotype manifest in F(1) offspring of crosses between two populations of Tribolium castaneum. Hybrid larvae cease development at the third larval instar, persisting as 'perpetually immature larvae' thereafter. Although unable to produce viable adult hybrid offspring with one another, each population produces abundant, fertile hybrids with other...
