Parasitic nature of extra fragment chromosomes
Parasitic nature of extra fragment chromosomes

This paper is intended as a contribution to the discussion concerning the significance of the extra fragments or »accessory chromosomes» as they are called by Håkansson(1945), which are not too rarely found in cross-fertilizing populations. I think reasonable support may he given to the view that in many cases these chromosomes have no useful function at all to the species carrying them, but that they often lead an exclusively parasitic existence.
