The B chromosomes of the grasshopper Eyprepocnemis plorans and the intragenomic conflict.
Genetica. 2003 Jan; 117(1):77-84.G

Abstract

The grasshopper Eyprepocnemis plorans harbours an extremely widespread polymorphism for supernumerary (B) chromosomes, which is found in almost all circum-Mediterranean and Caucasian populations hitherto analysed. B chromosomes in this species have been shown to evolve through several stages of parasitic and near-neutral nature, presumably because of an arms race between the standard (A) and B chromosomes. This intragenomic conflict can either be solved with the extinction of the neutralised B chromosome or, more interestingly, with the replacement of the neutralised B by a mutant version being parasitic again and thus prolonging B chromosome life. This species thus provides a complete view of the long-term life-cycle of parasitic B chromosomes.
