Spontaneous translocations between B chromosomes and the normal complement in the grasshopper Eyprepocnemis plorans

Abstract

A translocation between a B chromosome and a medium-size autosome and a centric fusion between the B and the X chromosome were found in two different natural populations of Eyprepocnemis plorans. The cytological behaviour of both interchanges is described and discussed. These interchanges are highly asymmetrical and may be the beginning of an integration of B chromosomes into the genome of this species.
