No detectable satellite DNA in supernumerary chromosomes of the grasshopper Myrmeleotettix

Nature volume 259, pages 57–59 (1976)Cite this article

Abstract

SUPERNUMERARY (B) chromosomes and satellite (simple sequence) DNA are enigmatic chromosomal phenomena, in that both are variable additions to the main chromosome complement. It has been suggested that differences between, and constancy within, certain related species for satellite DNA, implies that it may play a role in speciation by a series of saltatory steps1–3. Similarly, B chromosomes may affect recombination4 or rate of development5, or bring about diploidising effects in hybrids of closely related species6. There is still, however, no clear understanding of the functions of either of these variables.
