On the origin of B-chromosomes: Neo XY systems and X-like supernumeraries in Orthoptera

In previous diversification mechanisms of B-chromosomes were advanced, and conditions for their origin were summarized (GREEN 1990). In the present work, some examples of B-chromosomes in statu nascendi in grasshoppers with neo XY systems are cited, including two cases described in the present work...
