The frequency of rDNA variants within individuals provides evidence of population history and gene flow across a grasshopper hybrid zone.

Evolution; international journal of organic evolution - 1 Apr 2008

Keller Irene, Veltsos Paris, Nichols Richard A

Abstract excerpt

In the grasshopper Podisma pedestris, units of the ribosomal DNA (rDNA) multigene family are not identical, but comprise multiple genetic variants. We surveyed this variation using a novel pyrosequencing approach. The history of the study populations is well characterized as the pattern of colonization can be inferred from the distribution of two chromosomal races that invaded from different directions after the...
