POLYMORPHISM REGENERATION FOR A NEUTRALIZED SELFISH B CHROMOSOME.

S Zurita1, J Cabrero1, M D López-León1, J P M Camacho1.   

Abstract

Long-run evolution of B chromosomes is mainly made up by an evolutionary arms race between these selfish genetic elements and the standard genome. The suppression of B drive is one of the clearest expressions of genome defense against B chromosomes. After drive neutralization, the B is condemned to extinction unless a new variant showing drive can emerge and replace it. This paper reports the first empirical evidence for the substitution of a neutralized B variant by a new selfish B variant. Such a polymorphism regeneration has recently taken place in a natural population of the grasshopper Eyprepocnemis plorans. © 1998 The Society for the Study of Evolution.
