Population genetic structure of the grasshopper Eyprepocnemis plorans in the south and east of the Iberian Peninsula.

The grasshopper Eyprepocnemis plorans subsp. plorans harbors a very widespread polymorphism for supernumerary (B) chromosomes which appear to have arisen recently. These chromosomes behave as genomic parasites because they are harmful for the individuals carrying them and show meiotic drive in the i...
